The convenient transformation of acid chlorides into corresponding secondary α-ketoamides by the aminocarbonylation of acid chlorides with N-methoxymethyl-N-methylcarbamoyl(trimethyl)silane is described. The use of carbamoylsilane containing methoxymethyl group avoids the reaction of products α-ketoamides with carbamoylsilane in situ in the aminocarbonylation reaction. The methoxymethyl group was used
