Abstract:
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.
