An imine-coupled [Fe–N2S2]2 complex, prepared from a readily available benzothiazolidine ligand, catalyzes selectively the hydroboration of aliphatic and aromatic aldehydes at low catalyst loadings (0.1 mol %) using pinacolborane. Both mono- and disubstituted aromatic and aliphatic aldehydes are hydroborated selectively in the presence of ketones, nitriles, alkenes, amines, and halides. Reaction of the [Fe–N2S2]2 complex with CO and preliminary reaction progress kinetic studies point to a complex mechanism.

高效,选择性的铁络合物催化的硼氢化硼氢化

由易得的苯并噻唑烷配体制备的亚胺偶联的[Fe–N 2 S 2 ] 2络合物使用频哪醇硼烷在低催化剂负载量(0.1摩尔%)下选择性催化脂肪族和芳香族醛的氢硼化。在酮,腈,烯烃,胺和卤化物的存在下,单取代和二取代的芳族和脂族醛均被选择性地氢硼化。[Fe–N 2 S 2 ] 2与CO的反应以及初步的反应进展动力学研究指出了一种复杂的机理。
