Synthesis of alkyl N-(C-nitrosoaryl)carbamates and some reactions thereof

Reactions of alkyl N-phenylcarbamates, m-di(methoxycarboxyamido)benzene, and methyl N-(o-tolyl)carbamate with nitrosylsulfuric acid in glacial acetic acid afford N-(C-nitrosoaryl)carbamates; under these conditions tert-bulyl N-phenylcarbamate suffers decarboxylation, methyl N-(p-tolyl)-, methyl N-(p-methoxyphenyl)carbamates, o-and p-di(methoxycarboxyamido)benzenes are nitrated, and isomeric methyl N-nitrophenylcarbamates and methyl N-(p-bromophenyl)carbamate do not react. The reduction of N-(C-nitrosoaryl)carbamates with dithionite afforded the corresponding aminocarbamates; the oxidation with nitric acid yielded carbamate nitro derivatives; the condensation with aniline and benzylpyridinium chloride resulted in carbamate derivatives of azobenzene and phenylnitron.
