Treatment of Ï-azido acid chlorides with trimethylsilyl azide affords Ï-azido isocyanates which can be easily converted in good yields to the corresponding Ï-azidoamines or Ï-azidocarbamates. 1,3- and 1,4-Diamine dihydrochlorides can then be prepared by catalytic hydrogenation or reductive alkylation with an organodichloroborane.
