摘要

Abstract N-tert-Butyl-N-benzoylhydrazine was prepared in a new and convenient procedure with good yield. Triphosgene underwent reaction with three equivalents of Nt-butyl-N- benzoylhydrazine using six equivalents of triethylamine as a base to yield the cyclic tetramer of Nt-butyl-N-isocyanatobenzoylamide. Treatment of triphosgene with three equivalents of Nt- butyl-N-benzoylhydrazine either in the presence of three equivalents of triethylamine or in ...
