A synthesis is provided for &agr;,&bgr;-difluoro-&bgr;-halo-ethenyl aromatic compounds such as &agr;,&bgr;,&bgr;-trifluorostyrenes by a process of reacting CFX2CFXI, wherein each X is independently F or Cl, provided that at least one X is Cl and at least one X is F, with an aromatic compound Ar to form (CFX2CFX)n—Ar, wherein n is 1, 2 or 3, and subsequently dechlorohalogenating this product to form (CFX═CF)n—Ar. Novel synthetic intermediate compounds are provided.
提供了一种合成方法,用于合成α,β-二氟-β-卤乙烯芳香化合物,如α,β,γ-三氟苯乙烯,通过将CFX2CFXI与芳香化合物Ar反应而形成(CFX2CFX)n—Ar,其中n为1、2或3,其中每个X独立地为F或Cl,前提是至少一个X为Cl且至少一个X为F,然后对该产物进行去氯卤化处理以形成(CFXHCF)n—Ar。提供了新颖的合成中间体化合物。
