A palladium-catalyzed decarboxylative coupling of potassium cyanoacetate with aryl bromides and chlorides is described. The reaction conditions feature the absence of additional strong inorganic bases and provide ester functional group tolerance. With Pd(dba)2 and XPhos ligand as the catalyst system, α-diaryl nitriles can be obtained in good yields.
描述了氰基乙酸钾与芳基溴化物和氯化物的钯催化的脱羧偶联。反应条件的特征在于不存在额外的强无机碱并提供酯官能团耐受性。以Pd(dba)2和XPhos配体为催化剂体系,可以高收率获得α-二芳基腈。
