An efficient nickel‐catalyzed cross‐coupling of aryl pivalates with cyclobutanols is described. The use of Ni(cod)2/PCy3/base as the catalytic system enables the cleavage of inert C—O bond and C—C bond under mild conditions, thus providing a facile access to γ‐arylated ketones in generally good to excellent yields. This transformation is also characterized by wide substrate scope and functional group
描述了一种有效的镍催化新戊酸芳基酯与环丁醇的交叉偶联。通过使用Ni(cod)2 / PCy 3 /碱作为催化体系,可以在温和条件下裂解惰性C-O键和C-C键,从而可以轻松获得γ-芳基化的酮(通常良好或优异)产量。这种转化还具有广泛的底物范围和官能团相容性,例如在反应过程中可以很好地耐受甲氧基,N,N-二甲基氨基,酮基,酯基,氟基和TMS基团。
