固-液相转移催化α-溴代芳基乙腈的氧化偶联反应和二芳基乙腈的氧化脱氰反应(英文)

室温条件下以丙酮为溶剂,无水磷酸钾为碱,TBAB为催化剂,采用固-液相转移催化法实现α-溴代芳基乙腈的氧化偶联反应和二芳基乙腈的氧化脱氰反应。应用这种温和、简便的方法,可以高收率地得到α,β-二氰基芳乙烯和二芳基酮。

Oxidative coupling of α-bromoarylacetonitriles and oxidative decyanation of diarylacetonitriles catalyzed by solid-liquid phase transfer

Oxidative coupling of α-bromoarylacetonitriles and oxidative decyanation of diarylacetonitriles are efficiently realized by solid-liquid phase transfer catalysis using anhydrous K 3 PO 4 as base and TBAB as catalyst in acetone at room temperature. In this mild and convenient method, α,β-dicyanostilbenes and diarylketones were prepared in good to excellent yields.
