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.
由三元步骤的1,1-二甲基肼和α-氯烷基氯甲酸酯制备五元环的烷氧基氨基胺。加热后,这些氨基酰亚胺产生高产率的N,N-二甲基氨基异氰酸酯。该中间体在亲核试剂的存在下二聚化或被捕获。
