Palladium-catalyzed transfer semihydrogenation of alkynes using H2O as the hydrogen source and Mn as the reducing reagent is developed, affording cis- and trans-alkenes selectively under mild conditions. In addition, this method provides an efficient way to access various cis-1,2-dideuterioalkenes and trans-1,2-dideuterioalkenes by using D2O instead of H2O.
开发了使用H 2 O作为氢源和Mn作为还原剂的钯催化炔烃转移半氢化反应,在温和条件下选择性提供了顺式和反式烯烃。此外,此方法通过使用D 2 O代替H 2 O提供了一种有效的方法来访问各种顺式-1,2-杂二烯基烯烃和反式-1,2-杂二烯基烯烃。
