The activation of benzylic CH bonds and subsequent coupling with terminal alkynes in the presence of 2,3‐dichloro‐5,6‐dicyanoquinone (DDQ) and a catalytic amount of copper(I) triflate is presented. Good to moderate yields of disubstituted alkynes are obtained for this cross‐dehydrogenative coupling (CDC) reaction between a variety of aromatic alkynes and diphenylmethane derivatives.
介绍了在2,3-二氯-5,6-二氰基醌(DDQ)和催化量的三氟甲磺酸铜(I)存在下,苄基CH键的活化以及随后与末端炔的偶合。对于各种芳族炔烃和二苯甲烷衍生物之间的这种交叉脱氢偶联(CDC)反应,可获得良好至中等产率的二取代炔烃。
