摘要

tButjyl% substituted carbaeates have been prepared by acylation of substituted phenylhydrazines by meana of t-butyl azidofonnate in pyridine or by alkylation or acvlation of t-butyl carbazate. Oxidation of the appropriate hydrazo derivatives by means of N- bromosuccinimide and pyridine gave t-butyl phenyl-, p-bromophenyl-, pnitrophenyl-, emethoxyphenyland benwylazoformates. &Butyl hydrazodifomate gave t-butyl ...
