was employed in catalytic olefination reactions of aromatic aldehydes. In situ prepared hydrazones of aldehydes were transformed to β-fluoro-β-(trifluoromethyl)styrenes by reaction with CF3CFBr2 under CuCl catalysis. Based on this reaction, a novel stereoselective approach towards β-fluoro-β-(trifluoromethyl)styrenes was elaborated. Nucleophilic vinylic substitution of fluorine by secondary amines, thiolates
CF 3 CFBr 2用于芳族醛的催化烯化反应。通过与CF 3 CFBr 2在CuCl催化下反应,将原位制备的醛转化为β-氟-β-(三氟甲基)苯乙烯。基于该反应,阐述了针对β-氟-β-(三氟甲基)苯乙烯的新型立体选择性方法。还测试了β-氟-β-(三氟甲基)苯乙烯中仲胺,硫醇盐和醇盐对氟的亲核乙烯基取代。
