PREPARATION OF DIALKYLPYRIDYLBORANES

摘要

The present invention relates to method for the preparation of dialkylpyridylboranes by reacting a Grignard pyridine reagent with an alkoxydialkylborane or a trialkylborane. The reaction can be conducted at a temperature ranging from about 0.degree.C to about 40.degree.C. The Grignard pyridine reagent is preferably prepared in situ by the reaction of a Grignard reagent (RMgX) and an halopyridine in a suitable solvent, such as tetrahydrofuran, followed by the addition of an alkoxydialkylborane or a trialkylborane to form a dialkylpyridylborane.
