The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Tricyclohexylphosphonium tetrafluoroborate, is researched, Molecular C18H34BF4P, CAS is 58656-04-5, about Pd-Catalyzed Decarboxylative Cross-Coupling of 2-Carboxyazine N-oxides with Various (Hetero)aryl Halides, the main research direction is pyridine quinoline isoquinoline aryl preparation; 2-carboxyazine N-oxides; catalysis; cross-coupling; palladium.Electric Literature of C18H34BF4P.
Decarboxylation cross-coupling reactions of substituted 2-carboxyazine N-oxides, with a variety of heteroaryl halides or aryl halides, by bimetallic Pd0/CuI and Pd0/AgI catalysis are reported. Two possible pathways, a conventional bimetallic-catalyzed decarboxylation-arylation, as well as a protodecarboxylation direct carbon hydrogen bond (C-H bond) arylation sequence have been considered. These methods provide the first general decarboxylation-arylation methodol. for the 2-carboxyazine series. Under optimized conditions the synthesis of the target compounds was achieved using palladium bromide (PdBr2), tricyclohexylphosphine tetrafluoroborate and carbonic acid silver(1+) salt (1:2) (silver carbonate) or copper oxide (Cu2O) as catalyst combination. Starting materials included 2-quinolinecarboxylic acid 1-oxide, 4-methoxy-2-quinolinecarboxylic acid 1-oxide, isoquinoline 2-oxide, 2-pyridinecarboxylic acid 1-oxide. Aryl halides included 3-bromopyridine, bromobenzene, iodobenzene, 2-bromopyrazine, 2-iodopyrazine, 2-iodofuran. The title compds thus formed included biaryls, such as 2,3′-bipyridine 1-oxide, 2-(2-furanyl)pyridine 1-oxide, 2-(4-chlorophenyl)quinoline 1-oxide and related substances.
