Fujiwara, Yuta published the artcilePractical C-H Functionalization of Quinones with Boronic Acids, Formula: C9H12BClO3, the main research area is alkyl aryl quinone preparation natural product; quinone boronic acid coupling silver nitrate catalyst.

A direct functionalization of a variety of quinones with several boronic acids has been developed. This scalable reaction proceeds readily at room temperature in an open flask using catalytic silver(I) nitrate in the presence of a persulfate co-oxidant. The scope with respect to quinones is broad, with a variety of alkyl- and arylboronic acids undergoing efficient cross-coupling. The mechanism is presumed to proceed through a nucleophilic radical addition to the quinone with in situ reoxidation of the resulting dihydroquinone. This method has been applied to complex substrates, including a steroid derivative and a farnesyl natural product.

Gottumukkala, Aditya L. published the artcileEfficient Formation of Benzylic Quaternary Centers via Palladium Catalysis, Synthetic Route of 480438-56-0, the main research area is palladium catalyst conjugate addition arylboronic acid enone; CC coupling reactions; arylations; enones; ligands; palladium.

Pd(O2CCF3)2 and 2,2-bipyridine catalyzed the formation of benzylic quaternary centers from arylboronic acids and β-disubstituted enones. For cyclic substrates, only 1 mol% of palladium is required for full conversion, and a variety of arylboronic acids could be reacted with yields exceeding 90%. 5-Membered cyclic enones were found to be most reactive, followed by 6-membered rings and then 7-membered rings. E.g., reaction of 3-methyl-2-cyclohexenone and PhB(OH)2 gave 92% I. In the case of acyclic substrates, e.g. (E)-Me3COCH2CMe:CHCOMe, 5 mol% Pd was found to be necessary, along with the addition of 20 mol% KSbF6 to afford the highest conversion.

Seth, Kapileswar published the artcileCooperative Catalysis by Palladium-Nickel Binary Nanocluster for Suzuki-Miyaura Reaction of Ortho-Heterocycle-Tethered Sterically Hindered Aryl Bromides, Synthetic Route of 480438-56-0, the main research area is Suzuki Miyaura coupling sterically hindered aryl bromide boronic acid; palladium nickel binary nanocluster catalyst Suzuki Miyaura coupling.

The palladium-nickel binary nanocluster is reported as a new catalyst system for Suzuki-Miyaura cross-coupling of ortho-heterocycle-tethered sterically hindered aryl bromides. The inferior results obtained with the reported Pd/Ni salts/complexes or individual Pd/Ni nanoparticles as catalyst reveal the cooperative catalytic effect of the Pd and Ni nanoparticles in the Pd-Ni nanocluster. The broad substrate scope with respect to variation of the 2-arylbenzoxazole moiety and boronic acids, which offers a means for diversity generation and catalyst recyclability, marks a distinct advantage. E.g., in presence of palladium-nickel binary nanoclusters in DMF, Suzuki-Miyaura cross-coupling of PhB(OH)2 with sterically hindered aryl bromide (I) gave 80% II.

Purohit, Priyank published the artcileC-O Bond Activation by Nickel-Palladium Hetero-Bimetallic Nanoparticles for Suzuki-Miyaura Reaction of Bioactive Heterocycle-Tethered Sterically Hindered Aryl Carbonates, SDS of cas: 480438-56-0, the main research area is aryl carbonate arylboronic acid Ni Pd binary Suzuki Miyaura; biaryl heterocycle tethered preparation.

Ni-Pd binary nanoclusters are reported for the activation of the C-O bond for Suzuki-Miyaura cross-coupling of bioactive heterocycle-tethered sterically hindered aryl carbonates with aryl boronic acids. The reaction does not take place in the presence of either the Pd or Ni salts/complexes or the individual Pd or Ni nanoparticles, indicating ensembling cooperativity between the Pd and Ni nanoparticles in activating the C-O bond.

Karad, Somnath Narayan published the artcileEnantioselective Synthesis of Chiral Cyclopent-2-enones by Nickel-Catalyzed Desymmetrization of Malonate Esters, Recommanded Product: 3-Chloro-4-isopropoxyphenylboronic acid, the main research area is chiral cyclopentenone enantioselective synthesis; crystal mol structure phenyl cyclopentenone; nickel catalyzed desymmetrization alkynyl malonate ester arylboronic acid; asymmetric catalysis; carbocycles; cyclization; isomerization; nickel.

The enantioselective synthesis of highly functionalized chiral cyclopent-2-enones by the reaction of alkynyl malonate esters with arylboronic acids is described. These desymmetrizing arylative cyclizations are catalyzed by a chiral phosphinooxazoline/nickel complex, and cyclization is enabled by the reversible E/Z isomerization of alkenylnickel species. The general methodol. is also applicable to the synthesis of 1,6-dihydropyridin-3(2H)-ones.
