Efficient and Selective Iron-Complex-Catalyzed Hydroboration of Aldehydes

摘要: 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- disubstituted are hydroborated in presence ketones, nitriles, alkenes, amines, halides. Reaction complex with CO preliminary reaction progress kinetic studies point to mechanism.
