摘要：

Methods toward the dimerization and homocoupling of terminal alkynes have been established that employ Co complexes along with tBuOK under different atmosphere. A variety of Z-1,3-enynes were furnished with a high Z:E (up to 93:7) ratio in moderate to very good yields under inert atmosphere. Alternatively, the Glaser homocoupling reaction of terminal alkynes was also accomplished with a Co catalyst, successfully affording various 1,3-diynes in excellent yields (up to 93%) under oxygen.
