- Acyloxy group exchange in N-acyloxy-N-alkoxyamides
-
Acyloxy group exchange at the nitrogen atom proceeds in the interaction of N-acyloxy-N-alkoxyureas, N-acyloxy-N-alkoxybenzamides and N-acyloxy-N- alkoxycarbamates with Na and K carboxylates in MeCN.

- Geminal systems 50. Synthesis and alcoholysis of N-acyloxy-N-alkoxy derivatives of ureas, carbamates, and benzamides
-
Procedures were developed for the synthesis of N-acyloxy-N-alkoxy derivatives of ureas, carbamates, and benzamides by the reactions of the corresponding N-alkoxy-N-chloro derivatives with sodium carboxylates in MeCN. N-Chloro-N-ethoxy-p-toluenesulfonamide was inert in this reaction. Alcoholysis of N-acyloxy-N-alkoxy derivatives of ureas, carbamates, and tert-alkylamines afforded the corresponding N,N-dialkoxy derivatives, whereas alcoholysis of N-acetoxy-N-ethoxybenzamide gave rise to alkyl benzoates.
