近年来,我们在研究含氟烯烃和烷烃的红外激光诱导氧化和氯化反应的基础上,深入研究了红外激光诱导卤代烷烃的脱卤化氢并生成:CF_2卡宾和:CFCF_3卡宾的反应以往的研究往往是根据反应产物推论反应机理,认为在反应过程中存在着卡宾中间体,但在实验中未能直接检测到.Kakimoto曾报道过在流动体系中测到了·F+CH_3F和·F+CH_3Cl反应中:CHF和:CHCl的激光荧光激发谱,但没有讨论卡宾形成的机理.Hirota在讨论·F+CH_3F反应时,认为:CHF可能由攫氢过程产生而对于·F+CH_3Cl反应同时生成
In recent years, based on the infrared laser-induced oxidation and chlorination of fluoroolefins and paraffins, we have studied the dehydrohalogenation of halogenated alkanes induced by infrared laser and their formation: The previous studies on the reaction of CF_2 carbenes with CFCF_3 carbenes Often based on the corollary reaction mechanism of the reaction product, it is believed that there is a carbene intermediate present during the reaction but not directly detected in the experiment. Kakimoto reported measuring the F + CH_3F and F + CH_3Cl reactions in mobile systems In the discussion of the F + CH_3F reaction, Hirota argues that CHF may be generated by the hydrogen-grabbing process and simultaneously generated for the F + CH_3Cl reaction
