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