The three-component coupling of benzynes with terminal alkynes and activated alkenes in the presence of CuI, PCy(3) and CsF in a 1:1 mixture of CH(3)CN and THF at 50 degrees C for 5 h gave 1-alkyl-2-alkynylbenzenes in good to moderate yields.
在CuI,PCy(3)和CsF在CH(3)CN和THF的1:1混合物中于50°C的条件下在5小时下将苯炔与末端炔和活化烯烃的三组分偶联生成1烷基-2-炔基苯的收率良好至中等。
