COA of Formula: C18H24Cl2N2Pd2 The article mentions the following:

Bis-NHC precursors composed of an azolium and a 2-halogenoazole group connected by different linkers have been site-selectively metalated to give heterobimetallic complexes from a single-frame bis-NHC ligand. The azolium group reacts with a base and oxidized metal centers to give NHC complexes with no participation of the halogenoazole, while the halogenoazole reacts in an oxidative addition with low-valent transition metals to give azolato complexes with no participation of the azolium group. In addition to this study using Di-μ-chlorobis[2-[(dimethylamino)methyl]phenyl-C,N]dipalladium(II), there are many other studies that have used Di-μ-chlorobis[2-[(dimethylamino)methyl]phenyl-C,N]dipalladium(II)(cas: 18987-59-2COA of Formula: C18H24Cl2N2Pd2) was used in this study.

In 2021,New Journal of Chemistry included an article by Varmuzova, Vera; Horky, Filip; Stepnicka, Petr. Recommanded Product: Di-μ-chlorobis[2-[(dimethylamino)methyl]phenyl-C,N]dipalladium(II). The article was titled 《Synthesis and coordination of a hybrid phosphinoferrocene sulfonamide ligand》. The information in the text is summarized as follows:

In order to expand the family of hybrid phosphinoferrocene ligands, a novel phosphinoferrocene sulfonamide ligand, Ph2PfcNHSO2Me (1, fc = ferrocene-1,1′-diyl), was synthesized through a reaction between P-protected phosphinoamine Ph2PfcNH2·BH3 and MeSO2Cl followed by deprotection of the Ph2PfcNHSO2Me·BH3 (2) intermediate. Compound 1 coordinates as a functional phosphine ligand, producing Pd(II) complexes [PdCl(μ-Cl)(1-κP)]2 (4) or [PdCl2(1-κP)2] (5) from [PdCl2(cod)] (cod = cycloocta-1,5-diene) depending on the stoichiometry. The reaction of 1 with [(LNC)Pd(μ-Cl)]2 also produces a phosphine complex, [(LNC)PdCl(1-κP)] (6; LNC = 2-[(dimethylamino-N)methyl]phenyl-κC1), which was converted into the neutral bis-chelate complex [(LNC)Pd(Ph2PfcNSO2Me-κ2P,N)] (7) upon treatment with potassium tert-butoxide; the corresponding cationic chelate [(LNC)Pd(Ph2PfcNHSO2Me-κ2P,O)]+ could not be isolated. All compounds were characterized by elemental anal. and spectroscopic methods (NMR, IR and MS). In addition, the crystal structure of 1, 2, and 4-7 were determined (for solvated compounds in some cases), and the electrochem. properties of 1, 2, 6 and 7 were studied by cyclic voltammetry.

HPLC of Formula: 18987-59-2On May 1, 2022 ,《The thiosulfate (S2O2-3) ion; a neglected but simple hetero-donor ligand towards platinum(II), palladium(II) and nickel(II)》 appeared in Inorganica Chimica Acta. The author of the article were Kaewthong, Aphiwat; Saunders, Graham C.; Henderson, William. The article conveys some information:

Reactions of the thiosulfate ligand (as sodium thiosulfate, Na2S2O3·5H2O) with phosphine complexes of the group 10 metals Ni(II), Pd(II) and Pt(II) resulted in five neutral thiosulfate complexes, [Ni(S2O3)(dppe)] (dppe = Ph2PCH2CH2PPh2), [Pd(S2O3)(dppe)], [Pd(S2O3)(dppf)] (dppf = Fe(C5H4PPh2)2), [Pd(S2O3)(PPh3)2] and [Pt(S2O3)(PPh3)2]. X-ray structure determinations of [Pd(S2O3)(dppf)], [Pd(S2O3)(PPh3)2] and [Pt(S2O3)(PPh3)2] confirmed that thiosulfate ligand coordinates as a bidentate chelating ligand via both sulfur and oxygen donor atoms. In addition, reactions of the thiosulfate ligand with dinuclear chloride-bridged cyclopalladated complexes gave four mononuclear anionic complexes [Pd(S2O3)(damp)]- (damp = N,N-dimethylbenzylamino, (CH3)2NCH2C6H4), [Pd(S2O3)(ptpy)]- (ptpy = p-tolylpyridyl), [Pd(S2O3)(bzpy)]- (bzpy = 2-benzylpyridyl) and [Pd(S2O3)(pap)]- (pap = 2-(phenylazo)phenyl). The structure of (Ph3PCH2Ph)[Pd(S2O3)(pap)] by X-ray crystallog. revealed the ability of thiosulfate ligand to cleave the bridging chloride ligand on the starting complexes by acting as an S,O-donor chelating ligand. An ESI mass spectrometric study showed that the coordinated thiosulfate ligand undergoes fragmentation at elevated capillary exit voltages.

In 2019,European Journal of Inorganic Chemistry included an article by Dong, Jie; Wang, Baiquan. Electric Literature of C18H24Cl2N2Pd2. The article was titled 《Synthesis and Catalytic Properties of Cyclopalladated Complexes Bearing a Phosphane-Sulfonate Ligand》. The information in the text is summarized as follows:

Reactions of the phosphine-sulfonate ligand with [Pd(OAc)(8-Me-quin-H)]2 or [Pd(dmba)(μ-Cl)]2 (dmba = Me2NCH2C6H5) in MeCN afforded the corresponding C(sp3),N-chelated palladacycle Pd1 and C(sp2),N-chelated palladacycle Pd2 in high yields. Both complexes were fully characterized by 1H and 13C NMR, high-resolution mass spectrometry (HRMS), and elemental anal. The mol. structure of Pd1 was further confirmed by single-crystal x-ray diffraction anal. With Et2AlCl as cocatalyst, these complexes showed moderate catalytic activities for the addition polymerization of norbornene. While with methylaluminoxane (MAO) as cocatalyst, they showed high catalytic activities (up to 5.80 × 107 g of PNB (mol of Pd)-1 h-1) at higher temperatures (above 100°). The C(sp3),N-chelated palladacycle Pd1 exhibited marked higher activities than the C(sp2),N-chelated palladacycle Pd2, whether Et2AlCl or MAO was used as cocatalyst. The experimental part of the paper was very detailed, including the reaction process of Di-μ-chlorobis[2-[(dimethylamino)methyl]phenyl-C,N]dipalladium(II)(cas: 18987-59-2Electric Literature of C18H24Cl2N2Pd2)

Di-μ-chlorobis[2-[(dimethylamino)methyl]phenyl-C,N]dipalladium(II)(cas: 18987-59-2) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Electric Literature of C18H24Cl2N2Pd2

《Dinuclear Palladium(II) and Platinum(II) Complexes of a Readily Accessible Bicyclic Diphosphane》 was written by Edgar, Mark; Elsegood, Mark R. J.; Liu, Pingchuan; Miles, Christopher R.; Smith, Martin B.; Wu, Shimeng. Product Details of 18987-59-2 And the article was included in European Journal of Inorganic Chemistry on April 27 ,2022. The article conveys some information:

The one-step synthesis (33% isolated yield) of a novel bicyclic diphosphine I (P-P), from the reaction of [P(CH2OH)4]Cl and H2NC6H4-4-NMe2 in methanol is described. Surprisingly, P-P displays excellent air/solution stability (towards H2O, MeOH) and can also function efficiently as a bridging ligand. Hence reaction of P-P with [Pd(μ-Cl)(η3-allyl)]2 (η3-allyl = C3H5, C4H7) or [Pd(μ-Cl)(κ2-C9H12N)]2 affords the singly-bridged complexes {Pd(Cl)(η3-allyl)}2{μ-P-P} 1a/1b and {Pd(Cl)(κ2-C9H12N)}2{μ-P-P(NMe2)} 1c whereas treatment with [MX2(η4-cod)] (M = Pd, Pt; X = Cl, Br, I, Me; η4-cod = cycloocta-1,5-diene) gave (MX2)2{μ-P-P(NMe2)}2 (2a-2e) in high yields. Protonation of 2a-2d with HBF4·OEt2 gave the corresponding dimethylammonium salts 3a-3d. Single crystal X-ray studies have been undertaken on P-P(NMe2), 1b, 2a, 2b·2CDCl3, 2d, 2e, 3a·12CD3CN and 3b·12CD3CN. The P-P bond lengths in free/coordinated P-P(NMe2) remain similar across all compounds studied here and no M ··· M contacts were observed within the planar M2P4 ring. In 3a/3b the BF4- anion displays a unique secondary interaction with the inorganic six-membered M2P4 core.

Yang, Chao; Gao, Yadong; Bai, Songlin; Jiang, Chao; Qi, Xiangbing published an article in Journal of the American Chemical Society. The title of the article was 《Chemoselective Cross-Coupling of gem-Borazirconocene Alkanes with Aryl Halides》.Synthetic Route of C18H24Cl2N2Pd2 The author mentioned the following in the article:

The direct and chemoselective conversion of the C-metal bond of gem-dimetallic reagents enables rapid and sequential formation of multiple C-C and C-heteroatom bonds, thus representing a powerful method for efficiently increasing structural complexity. Herein, the authors report a visible-light-induced, Ni-catalyzed, chemoselective cross-coupling reaction between gem-borazirconocene alkanes and diverse aryl halides, affording a wide range of alkyl Bpin derivatives in high yields with excellent regioselectivity. This practical method features attractively simple reaction conditions and a broad substrate scope. Addnl., the authors systematically studied a Bpin-directed chain walking process underlying the regioselectivity of alkylzirconocenes, thus uncovering the mechanism of the remote functionalization of internal olefins achieved with the authors’ method. Finally, DFT calculations indicate that the high regioselectivity of this reaction originates from the directing effect of the Bpin group.
