One-pot synthesis of ketones from carboxylic acids and grignard reagents using N,N-Diphenyl-p-methoxyphenylchloromethyleniminium chloride

N,N-Diphenyl-p-methoxyphenylchloromethyleniminium chloride is found to be an effective condensation reagent of carboxylic acids and Grignard reagents under mild conditions to afford the corresponding ketones in high yields.
