Abstract
The present invention describes chemical systems and methods for silylating heteroaromatic organic substrates, said system consisting essentially of a mixture of (a) at least one organodisilane and (b) at least alkoxide base, preferably a potassium alkoxide base, and said methods comprising contacting a quantity of the organic substrate with a mixture consisting essentially of (a) at least one organodisilane and (b) at least one alkoxide base, preferably a potassium alkoxide, under conditions sufficient to silylate the heteroaromatic substrate.
