New approach to N,N-dialkoxy-N′-arylureas and N,N-dialkoxycarbamates

Abstract

Methanolysis of N-chloro-N-alkoxy-N’-arylureas in the presence of silver trifluoroacetate gives the corresponding N,N-dialkoxy-N’-arylureas, whereas N-chloro-N-alkoxycarbamates react with alcohols in the presence of silver trifluoroacetate to afford N,N-dialkoxycarbamates.
