摘要

α-Arylcarboxylic acid amides were synthesized by reacting silyl enol ethers of aryl ketones and 2-azido-1, 3-dimethylimidazolinium hexafluorophosphate (ADMP, 1). Silyl enol ethers react with ADMP 1 to give N-(α-arylacyl) guanidines via the migration of aryl groups in enol ethers. The products were transformed to the corresponding α-aryl acetamides by treating with LiAlH 4.
