Treatment of N-substituted formamides with chlorophosphate compounds such as PhOPOCl2, EtOPOCl2, Me2NPOCl2, and (PhO)2POCl and tertiary amines such as triethylamine, pyridine, and N,N-diisopropylethylamine produced the corresponding isocyanides in high yields. This method can be used to prepare various alkyl and aryl isocyanides. isocyanide - isonitrile - formamide - dehydration - dichlorophosphate
与氯磷酸的N-取代的甲酰胺的治疗化合物如PhOPOCl 2,EtOPOCl 2中,Me 2 NPOCl 2,和(PHO)2的POCl和叔胺如三乙胺,吡啶,和Ñ,Ñ二异丙基乙胺所产生的相应的以高收率异氰化物。该方法可用于制备各种烷基和芳基异氰酸酯。 异氰化物-异腈-甲酰胺-脱水-二氯磷酸酯-一氯磷酸酯
