• The reactions of isocyanides with alkyl hypochlorite, <I>N</I>-bromoamides, and hydroxylamine have been investigated. Cyclohexyl and phenyl isocyanides give <I>t</I>-butyl carbamates (urethanes) by the zinc chloride-catalyzed reaction with <I>t</I>-butyl hypochlorite, followed by treatment with water. An analogous reaction with <I>N</I>-bromosuccinimide or <I>N</I>-bromoacetamide in the presence of a small amount of water gives the corresponding acylureas. On treatment with hydroxylamine hydrochloride and zinc chloride, cyclohexyl isocyanide affords <I>N</I>-cyclohexylurea.
