Diaryl hydrazides prepared from the Pd(0)- or Cu(I)-catalyzed coupling reactions of aryl hydrazides and aryl halides underwent the acid-catalyzed rearrangements to a series of previously unknown 2,2‘-diaminobiaryls in good overall yields. The mildness of the reaction conditions allows the presence of various functional groups.
由芳基酰肼和芳基卤化物经Pd(0)或Cu(I)催化的偶联反应制得的二芳基酰肼经过酸催化重排后生成了一系列未知的2,2'-二氨基联芳基,总收率很高。反应条件的温和性允许存在各种官能团。
