Chlorobenzenes are important starting materials for the preparation of com. valuable triarylphosphines and tetraarylphosphonium salts, but their use for the direct arylation of elemental phosphorus has been elusive. Here we describe a simple photochem. route toward such products. UV-LED irradiation (365 nm) of chlorobenzenes, white phosphorus (P4) and the organic superphotoreductant tetrakis(dimethylamino)ethylene (TDAE) affords the desired arylphosphorus compounds in a single reaction step.

Molander, Gary A.; Wisniewski, Steven R. published the artcile< Stereospecific Cross-Coupling of Secondary Organotrifluoroborates: Potassium 1-(Benzyloxy)alkyltrifluoroborates>, Formula: C6H3ClF2, the main research area is aldehyde copper diboration benzylation alkoxylation acylation; potassium acyloxy alkoxyalkyltrifluoroborate preparation palladium arylchloride heteroarylchloride Suzuki Miyaura; aryl acyloxy alkoxy secondary alc stereospecific preparation; stereospecific retention Suzuki Miyaura catalyst palladium preparation.

Potassium 1-(alkoxy/acyloxy)alkyltrifluoroborates have been synthesized through a copper-catalyzed diboration of aldehydes and subsequent conversion of the resulting potassium 1-(hydroxy)alkyltrifluoroborates. The palladium-catalyzed Suzuki-Miyaura reaction employing the potassium 1-(benzyloxy)alkyltrifluoroborates with aryl and heteroaryl chlorides provides access to protected secondary alcs. in high yields. The β-hydride elimination pathway is avoided through use of the benzyl protecting group, which is proposed to stabilize the diorganopalladium intermediate by coordination of the arene to the metal center. This cross-coupling is stereospecific with complete retention of stereochem.

Oda, Susumu; Kumano, Wataru; Hama, Toshiki; Kawasumi, Ryosuke; Yoshiura, Kazuki; Hatakeyama, Takuji published the artcile< Carbazole-Based DABNA Analogues as Highly Efficient Thermally Activated Delayed Fluorescence Materials for Narrowband Organic Light-Emitting Diodes>, Formula: C6H3ClF2, the main research area is carbazole DABNA delayed fluorescence TADF OLED electroluminescent device; borylation; carbazole; organic light-emitting diodes; organoboron; thermally activated delayed fluorescence.

Carbazole-based DABNA analogs (CzDABNAs) were synthesized from triarylamine by regioselective one-shot single and double borylation. The reaction proceeded selectively at the ortho position of the carbazolyl group, where the HOMO is mainly localized owing to the difference in the electron-donating abilities of the diarylamino and carbazolyl groups. The facile and scalable method enabled synthesis of CzDABNAs, exhibiting narrow-band thermally activated delayed fluorescence with emission spectra ranging from deep blue to green. The organic light-emitting diode devices employing these products as emitters exhibited deep-blue, sky-blue, and green emission with high external quantum efficiencies of 19.5, 21.8, and 26.7%, resp.

Molander, Gary A.; Trice, Sarah L. J.; Kennedy, Steven M.; Dreher, Spencer D.; Tudge, Matthew T. published the artcile< Scope of the Palladium-Catalyzed Aryl Borylation Utilizing Bis-Boronic Acid>, Category: chlorides-buliding-blocks, the main research area is palladium catalyzed borylation aryl halide bisboronic acid; aryl fluoroborate preparation; boronic acid aryl preparation reaction; hydride reduction aryl halide palladium catalyst.

The Suzuki-Miyaura reaction has become one of the more useful tools for synthetic organic chemists. Until recently, there did not exist a direct way to make the most important component in the coupling reaction, the boronic acid. Current methods to make boronic acids often employ harsh or wasteful reagents to prepare boronic acid derivatives and require addnl. steps to afford the desired boronic acid. The scope of the previously reported Pd-catalyzed, direct boronic acid synthesis is unveiled, which includes a wide array of synthetically useful aryl electrophiles. It makes use of the newly available 2nd generation Buchwald XPhos preformed Pd catalyst and bis-boronic acid. For ease of isolation and to preserve the often sensitive C-B bond, all boronic acids were readily converted to their more stable trifluoroborate counterparts.

Lei, Xiangyang; Obregon, Karla A.; Alla, Jhansi published the artcile< Suzuki-Miyaura coupling reactions of aryl chlorides catalyzed by a new nickel(II) σ-aryl complex>, Application In Synthesis of 1435-43-4, the main research area is aryl chloride Suzuki coupling nickel aryl complex catalyst.

A new nickel(II) σ-aryl complex, trans-chloro(9-phenanthrenyl)bis(triphenylphosphine)nickel(II), was used as a precatalyst for the Suzuki-Miyaura coupling reactions of aryl chlorides. The catalytic conditions were optimized by investigating the cross-coupling of p-chloroanisole with phenylboronic acid. The results show that this complex is efficient for both electron-rich and electron-deficient aryl chlorides, though it gives better yields for activated arylboronic acids than deactivated ones. All isolated cross-coupled biaryl products have been characterized by 1H and 13C NMR, and their spectral data are consistent with those reported. Side products from the coupling of arylboronic acid with the precatalyst complex have also been isolated and characterized, which is helpful for understanding the coupling mechanism.

Wu, Ni; Xiao, Hui; Lou, Yuheng; Han, Mingxi; Guo, Zhiyong; Zhan, Hongbing published the artcile< Manipulating the Position of Triplet Chromophores To Achieve a Dynamic Photoactivated Ultralong Organic Phosphorescence Effect>, HPLC of Formula: 1435-43-4, the main research area is triplet chromophore photoactivated ultralong organic phosphorescence effect.

Pure organic materials with room-temperature phosphorescence (RTP) have promising applications in bioimaging, information storage, and encryption. However, these materials are still very scarce due to a lack of design guidelines. Herein, a series of com./lab-synthesized carbazole-based derivatives is prepared by manipulating the positions of the chlorine substituents on the Ph ring. The results show that 4CDCzB-Cm and 5CDCzB-Cm have ultralong phosphorescence lifetimes of 699.13 and 710.96 ms with good conjugation, longer than lab-synthesized ones due to the existence of isomers in the com. samples. Remarkably, 2CDCzB-Cm shows photoactivated ultralong RTP with increased lifetimes from 51.24 to 631.83 ms by manipulating intermol. interactions upon UV irradiation The phosphor can also be deactivated back to its original state after standing in the dark for 5 h. The extraordinary photoresponsive and highly reversible properties of 2CDCzB-Cm provide a significant step forward in expanding the scope of organic phosphorescence applications.
