The supported copper hydroxide catalyst on manganese 2 oxide-based octahedral molecular sieve OMS-2 (Cu(OH)(x)/OMS-2) was designed on the basis of the concept of coupled electron transfer. OMS-2 could act as not only a support for copper hydroxide species but also an electron-transfer mediator (cocatalyst) to generate a rapid electron-transfer path from an alkyne to dioxygen. As a result, Cu(OH)(x)/OMS-2 showed high catalytic performance (TOF = 540 h(-1), total TON = 666, and selectivity >99%) and long life (13 times reuse) for aerobic oxidative alkyne homocoupling.
