Reaction of higher dialkyl(methylthio)boranes with bromine: a new synthesis of dialkylbromoboranes
Abstract
Higher dialkyl(methylthio)boranes, readily prepared in situ from the corresponding trialkylboranes, react rapidly at low temperature with bromine to give dialkylbromoboranes and dimethyl disulphide. Removal of the latter under reduced pressure gives a pure product in excellent yield.
