CYCLIC CARBALKOXY AMINIMIDES. SYNTHESIS AND THERMAL DECOMPOSITION TO GIVE N,N-DIMETHYLAMINO ISOCYANATE

Article abstract of DOI:10.1016/S0040-4039(00)87797-7

Five membered ring carbalkoxy aminimides are prepared from 1,1-dimethylhydrazine and α-chloroalkyl chloroformates in three steps.Upon heating, these aminimides give high yields of N,N-dimethylamino isocyanate.This intermediate dimerizes or can be trapped in the presence of a nucleophile.
