iridium-catalyzed semihydrogenation of alkynes to E- and Z-alkenes with ethanol was developed. Effective selectivity control was achieved by ligand regulation. The use of 1,2-bis(diphenylphosphino)ethane (DPPE) and 1,5-cyclooctadiene (COD) was critical for the stereoselective semihydrogenation of alkynes. The general applicability of this procedure was highlighted by the synthesis of more than 40 alkenes, with
开发了由配体控制的铱催化的炔烃用乙醇半氢化为E-和Z-烯烃的方法。通过配体调节实现了有效的选择性控制。1,2-双(二苯基膦基)乙烷(DPPE)和1,5-环辛二烯(COD)的使用对于炔烃的立体选择性半氢化反应至关重要。通过合成具有良好立体选择性的40多种烯烃,突出了该方法的一般适用性。通过研究pinosylvin和4,4'-dihydroxystilbene(DHS)对作为脊椎动物模型的斑马鱼的影响,研究了我们的方法在实际应用中的价值。
