Imidoyl chlorides (generated from isocyanides and acyl chlorides) reacts with triisopropyl phosphite, in a Perkow-type reaction, to produce 1-alkoxycarbonyl-2-(alkylimino)vinyl diisopropyl phosphate, which undergo a smooth reaction with bidentate nucleophilic intermediates obtained from the reaction between malononitrile and heterocumulenes, such as arylisothiocyanates or carbon disulfide to produce
亚胺基氯(由异氰化物和酰氯生成)与亚磷酸三异丙基酯在Perkow型反应中反应,生成1-烷氧基羰基-2-(烷基亚氨基)乙烯基二异丙基磷酸,与从反应中获得的二齿亲核中间体进行平稳反应在丙二腈和杂枯烯(例如芳基异硫氰酸酯或二硫化碳)之间产生含2-二氰基亚甲基-2,3-二氢噻唑和2-二氰基亚甲基-1,3-二硫基部分的极化烯烃。
