You do not fear death,but sometimes you wish for it.

你不怕死，但有时候你却想死。

For the next step, the fluoroalkylated triazo-compounds (RFCH2N3) reacted with triphenylphosphine affording fluoro phosphorous imines, N-Wittig reagents. The reactions of these reagents with CO2 and CS2 were studied.

氟烷基叠氮化合物和PPh3室温下反应得到中间体磷亚胺化合物，并初步研究了与CO2、CS2的氮杂-Wittig反应。
