Abstract
Reaction of dialkylnickel complexes, NiR2L2 (R = CH3, C2H5, C3H7; L = 1/2 (2,2′-bipyridine), 1/2[1,2-bis(diphenylphosphino)ethane], triethylphosphine) with carbon monoxide give ketones, diketones and aldehydes depending on the reactivity of the dialkylnickel complexes and the reaction temperature. Nickel complexes NiY2L2 (Y = halogen or alkyl; L = ligand) catalyze formation of ketones and tertiary alcohols from Grignard reagents, aryl halides, and carbon monoxide.Keywords
