An extension of the scope of the Grignard reaction of fluorinated compounds is reported. Fluorohalogenoethanes of the general formula CF3CXYZ ( X = F,Cl,Br ; Y,Z = Cl,Br ) were found to undergo smoothly the metal-halogen exchange reaction with alkyl- or aryl-magnesium halides at low temperature to yield organometallic compounds CF3CXYMgHal. The Grignard compounds were reacted with a series of aldehydes
据报道,氟化化合物的格氏反应的范围扩大了。发现通式为CF 3 CXYZ(X = F,Cl,Br; Y,Z = Cl,Br)的氟卤乙烷在低温下能与烷基或芳基镁卤化物平稳地进行金属-卤素交换反应,从而生成有机金属化合物CF 3 CXYMgHal。使格氏试剂与一系列醛和酮反应,以良好至中等的制备产率得到相应的醇。
