Phenylglyoxal reacts with N-benzyloxy-N'-(2-bromopheny)urea forming N-[(benzoyl)(hydroxy)methyl]-N-benzyloxy-N'-(2-bromophenypurea. As it was found by XRD study, the molecules of the latter in crystal exist in two forms which vary in a different degree of pyramidality of the same nitrogen atom. Reactions of N-ethoxy-N'-phenylurea and N-benzyloxy-N'-(4-nitrophenyl)urea with phenylglyoxal lead to cyclic products.

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.
