Embodiments of the present disclosure relate generally to novel achiral and chiral sulfur-, nitrogen- and phosphorus-containing ligands, designated as NNS-type, P(O)NS-type, PNS-type, SNNS-type, SNNP(O)-type, or SNNP-type polydentate ligands and transition metal complexes of these ligands, including iridium complexes having PNS-type and NNS-type ligands. The catalysts derived from these ligands and transition metal complexes may be used in a wide range of catalytic reactions, including hydrogenation and transfer hydrogenation of unsaturated organic compounds, dehydrogenation of alcohols and boranes, various dehydrogenative couplings, chemoselective hydrogenation of α,β-unsaturated alcohols, and other catalytic transformations.
本公开的实施方案一般涉及新型非手性和手性含硫、氮和磷配体,即NNS型、P(O)NS型、PNS型、SNNS型、SNNP(O)型或SNNP型多齿配体以及这些配体的过渡金属配合物,包括具有PNS型和NNS型配体的铱配合物。由这些配体和过渡金属配合物衍生的催化剂可用于多种催化反应,包括不饱和有机化合物的氢化和转移氢化、醇和硼烷的脱氢、各种脱氢偶联反应、α,β-不饱和醇的化学选择性氢化以及其他催化转化反应。
