(2)CHaNFz=HF+CHzNF(二氟氨基上加甲基)。我们决定对反应(1)使用相同的技术。1：1的丙烯-NzF4混合物在2托(可能的最低压力)下在408K下在Monel反应罐中加热30min，并用气相色谱进行分析。98%的丙烯转化为1，Z-DP，2%的丙烯转化为亚胺，亚胺产物(1)损失2摩尔的氢氟化氢得到亚胺。我们建议采用以下机制[4]：
(2) CHaNFz= HF+ CHzNF by chemical activation (adding methyl to difluoramino radicals). We decided to use the same technique for reaction (1). A 1: 1 mixture of propylene-NzF4 at 2 torr (the lowest pressure possible) was heated for 30 minutes at 408 K in a Monel reaction vessel and was analyzed by gas chromatography. 98% of the propylene was converted to 1, Z-DP and2% of the propylene was converted to the iminonitrile obtained by loss of two moles of HF from the imine product of reaction (1). We suggest the following mechanism [4]:
