Tetrafluoroalkyl bromides are metalated with equimolar iPrMgCl·LiCl (Turbo Grignard) to form organomagnesium compounds which are stable at low temperatures and react with various electrophiles (aldehydes, ketones, CO2, cyclic sulfate and sulfamidate, N-sulfonylimines, nitrone, chlorophosphate, nonaflyl azide) to afford novel functionalized tetrafluoroethylene-containing products. Ease of operation
Tetrafluoroalkyl溴化物用等摩尔金属化我PrMgCl·LiCl(涡轮格利雅),以形成有机镁在低温下是稳定的,与各种亲电反应(醛,酮,CO的化合物2,环硫酸酯和磺酰胺酯,Ñ -sulfonylimines,硝酮,氯磷酸,叠氮化物)以提供新颖的官能化的含四氟乙烯的产物。易于操作,出色的选择性,高亲核性和增强的反应物种稳定性以及广泛的底物范围构成了极具吸引力的亲核四氟乙基化方案,可提供独特的合成构件。
