We present an important opinion about the electron effect of the intermolecular cyclcotrimerization of unsymmetrical diaryalkynes in the presence of Co2(CO)8 on the production of corresponding 1,2,4-regioisomer or 1,3,5-regioisomer derivatives with excellent yields and high regioselectivity.

炔烃的分子间[2 + 2 + 2]环三聚反应对多取代苯衍生物的高效区域选择性方法

我们提出了关于在Co 2(CO)8存在下不对称二芳炔的分子间环三聚的电子效应的重要观点,该电子对产生具有优异产率的相应1,2,4-区域异构体或1,3,5-区域异构体衍生物的影响和高区域选择性。
