Phenyl(1-bromo-1,2,2,2-tetrafluoroethyl)mercury has been prepared by reaction of phenylmercuric chloride and 1-bromo-1,2,2,2-tetrafluoroethane with sodium methoxide in THF at -35°. This mercurial readily transferred CF3CF to carbenophiles at 155°. With olefins good yiels of gem-fluoro(trifluoromethyl) cyclopropanes were obtained and with triethylsilane Si insertion gave Et3SiCHFCF3. On reaction with
通过使苯基汞氯化物和1-溴-1,2,2,2-四氟乙烷与甲醇钠在THF中在-35°下反应制得苯基(1-溴-1,2,2,2-四氟乙基)汞。此汞容易在155°下将CF 3 CF转移至嗜碳菌。用烯烃得到良好的宝石-氟(三氟甲基)环丙烷收率,用三乙基硅烷Si 3插入得到Et 3 SiCHFCF 3。上与thiobenzophenone反应中,硫的中间thurane后行损失,得到博士2 CCFCF 3。在PhHgCFBrCO 2的反应中也有类似的观察与硫代二苯甲酮和硫代芴酮一起。还制备了苯基(1-溴-1,2,2,-三氟-2-乙氧基乙基)汞,但该化合物没有显示二价碳转移反应性。
