Significance

A stable available pyridine-borane complex after the reaction with iodine gives a selective hydroborating agent, active at room temperature. Acetylenes can be transformed into ketones after oxidation. Mono-, di- and trisubstitut­-ed alkenes can be readily hydroborated leading to mono-adducts at room temperature. Functional groups like esters, amines and amides are tolerated.
