摘要
The CO_2 laser induced room temperature reactions of CH_3CF_2H or another protium-donor CH_3CHClCH_3 with chlorine-atom donors (Z--Cl) CFCl_2CF_2Cl, CF_3CCl_3, CFCl_3 or CF_2Cl_2, have been investigated. Some of these reactions can yield two important monomers (CF_2=CH_2 and CF_2=CFCl) for fluoropolymers simultaneously. The yield dependence of these two alkenes on experi- mental conditions has been studied. A laser-initiated chain process is supported by identifica- tion of Z--H intermediates in these reactions.
