N-Acetyl-N'-aryl(heteryl)ureas were synthesized by reaction of N-(1-hydroxyimino-2-oxopropyl)pyridinium chloride with amines.The use of amines on a silica support considerably increases the yield of acetylureas.

Aryl isothiocyanates and arylisocyanates react with N,O-bis(trimethylsilyl)acetamide to give N-methyl-N'-arylthioureas and ureas.Also nucleophilic additions of other aprotic nucleophiles (e.g.N-trimethylsilylimidazole, N-trimethylsilylpiperidine and N-trimethylsilylmorpholine) to the N=C=X (X=O,S) group were investigated.
