  铱钳制以乙烯为氢受体的醚催化脱氢

  摘要：

  We describe efficient methods to dehydrogenate ethers by using iridium pincer complexes ((ipr4)Anthraphos)-Ir(H)(Cl), 4, (PC)-P-ipr4(sp(3))P-Ir(H)(Cl) 5, and ((PCP)-P-ipr4)-Ir(H)(Cl), 6. At 120 degrees C, cyclic ethers were dehydrogenated with high turnover numbers (over 400 in many cases). Acyclic ethers such as diethyl ether can also be dehydrogenated catalytically with TONs up to 90. The efficient dehydrogenation of cyclic and acyclic ethers using ethylene as a more practical hydrogen acceptor has been demonstrated for the first time.
