Photochemical reactions of trichlorosilane, methyldichlorosilane, or trimethylsilane with vinyl fluoride gave the corresponding 2-fluororoethylsilanes (90–95% yields), hydrolysis or pyrolysis of which occurred viaβ-elimination of fluorine. The photochemical reaction of trichlorosilane with 1-chloro-2-fluoroethylene gave both 1:1 adducts. These were reduced by further reaction with silanes (SiHCl3,
三氯硅烷,甲基二氯硅烷或三甲基硅烷与氟乙烯的光化学反应产生了相应的2-氟甲基乙基硅烷(产率为90-95%),其水解或热解是通过氟的β-消除作用进行的。三氯硅烷与1-氯-2-氟乙烯的光化学反应产生了1:1的加合物。通过与硅烷(SiHCl 3,MeSiHCl 2或Me 3 SiH)进一步反应将其还原,得到同分异构的氟乙基三氯硅烷;β-氯的提取发生率是α-氯的提取率的3·5倍。的CH水解2 ·F·氯仿·的SiCl 3和CH 2氯·CHF·的SiCl 3发生经由β-消除卤素,分别得到氯乙烯和氟乙烯。三甲基硅烷与1-氯-2-氟乙烯反应生成氯三甲基硅烷,2-氯-1-氟乙基三甲基硅烷和1-氟乙基三甲基硅烷。回收的烯烃包含氟乙烯。
