We have described the first successful application of non-N-donor heterodonor ligands—thioether-phosphite ligands—in the Ir-catalyzed hydrogenation of minimally functionalized olefins. Excellent enantioselectivities (ee's up to 99%) have been obtained for a range of substrates, including challenging terminal disubstituted substrates, under standard conditions.

氢化中的第一次成功应用。在标准条件下,对于一系列底物,包括具有挑战性的末端二取代底物,获得了极好的对映选择性(对映体过量高达99%)。
