With air as the oxidant, terminal alkynes can be directly cross-coupled with alkylzinc reagents in the presence of a Pd catalyst at room temperature. CO was found to be critical in gaining high chemical yields and selectivities. A wide range of alkynes and alkylzinc reagents were tested, and good to excellent yields were obtained.
在空气中作为氧化剂的条件下，末端炔烃可以在钯催化剂的存在下于室温下直接与烷基锌试剂交叉偶联。研究发现 CO 在获得高化学收率和选择性方面是至关重要的。我们测试了广泛的炔烃和烷基锌试剂，得到了良好至优秀的产率。
