摘要

Combination of 3, 5-dimethyl-1-(2-(diphenylphosphino) phenyl)-1H-pyrazole, A, and 3-tert- butyl-5-methyl-1-(2-(diphenylphosphino) phenyl)-1H-pyrazole, B, with Pd2 (dba) 3 furnished excellent catalysts for Stille, Kumada and Hiyama cross-coupling reactions. Effects of solvents, bases and ligand/palladium ratio on efficiency of coupling reactions were studied. Molecular structures of palladium (II) complexes of A and B determined by single-crystal X ...
