We have replaced the oxazoline group with a thiazoline moiety in one of the most successful of the phosphite–oxazoline ligand families for the Ir‐catalyzedhydrogenation of minimallyfunctionalizedolefins. A small but structurally important library of Ir phosphite–thiazoline precatalysts (Ir‐L1–L2 a–e) has been developed by changing the substituents/configurations at the biaryl phosphite group. We
我们已经用噻唑啉部分取代了恶唑啉基团,这是亚磷酸酯-恶唑啉配体家族中最成功的一种,用于最小功能化烯烃的Ir催化加氢。通过改变亚磷酸联芳酯基团的取代基/构型,开发了一个小的但在结构上很重要的亚磷酸Ir-噻唑啉预催化剂库(Ir- L1 - L2 a - e)。我们发现在配体设计中用噻唑啉部分取代恶唑啉在底物范围方面是有益的。
