Abstract
A series of aryl-difluorophosphoranes are converted to give fluorophosphonium salts Ph2PF(o-C6X4BR2) (X = H, F; R = Cy, Mes). The proximity of the two weakly Lewis acidic fluorophosphonium and borane moieties results in enhanced Lewis acid catalytic reactivity.
摘要
一系列芳基二氟磷烷经转化得到氟鏻盐Ph2PF(o-C6X4BR2)（X = H，F；R = Cy，Mes）。两个弱路易斯酸性的氟鏻和硼烷部分的邻近导致路易斯酸催化反应活性增强。
