Recent advances in alkaline earth metal catalyzed hydroboration reactions

Abstract

Hydroboration, namely the direct addition of B-H bonds across C=O, C=N, C=C, C≡C and C≡N etc ., unsaturated bonds, is one of important methods for preparing organoborane compounds. Recently, the alkaline earth metal complexes have been widely employed as efficient catalysts for the hydroboration reaction. This article summarizes recent advancements in the alkaline earth metal (especially magnesium) catalyzed hydroboration of unsaturated organic compounds such as aldehydes, ketones, esters, amines, pyridines, nitriles, alkenes, alkynes, carbonates.
