The first general palladium‐catalyzed α‐arylation of arylacetonitriles with aryl and heteroaryl sulfonates are reported. The catalyst system comprising of Pd(OAc)2 and XPhos is highly effective towards this reaction. A wide range of aryl/heteroaryl tosylates and mesylates are coupled with arylacetonitriles smoothly and catalyst loadings as low as 0.1 mol‐% Pd can be achieved.
据报道,第一个普通的钯催化的芳基乙腈与芳基和杂芳基磺酸盐的α-芳基化反应。由Pd(OAc)2和XPhos组成的催化剂体系对该反应非常有效。各种各样的芳基/杂芳基甲苯磺酸酯和甲磺酸酯与芳基乙腈平滑地偶联,催化剂负载量可低至0.1 mol%Pd。
