Abstract
As a new transformation of organosulfur compounds, intramolecular desulfitative coupling of diaryl sulfones to the corresponding biaryls has been developed with the aid of nickel-NHC catalysts. This catalytic elimination of SO was also applicable to alkenyl aryl sulfone to furnish the corresponding alkenyl arene.
摘要
作为有机硫化合物的一种新转化，在镍-NHC 催化剂的辅助下，二芳基砜发生分子内脱磺化偶联反应，生成相应的联芳烃。这种 SO 的催化消除也适用于烯基芳基砜，得到相应的烯基芳烃。
