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