Palladium salicylaldimine complexes derived from 2,3-dihydroxybenzaldehyde
摘要:
Schiff bases derived from condensation of 2,3-dihydroxybenzaldehyde with various primary amines, such as 1-adamantanamine hydrochloride, 2,6-dimethylaniline, 2,6-diethylaniline and 2,6-diisopropylaniline, react with palladium(II) acetate to give the corresponding bis(N-arylsalicylaldiminato)palladium(II) complexes. These complexes have been found to be active catalyst precursors for the Suzuki-Miyaura cross-coupling of aryl bromides and iodides with aryl boronic acids using water as a solvent.
