Abstract
The present invention is directed to compositions for silylating organic substrates containing C—H or O—H bonds, especially heteroaromatic substrates. The compositions are derived from the preconditioning of mixtures of hydrosilanes or organodisilanes with bases, including metal hydroxide and metal alkoxide bases. In some embodiments, the preconditioning results in the formation of reactive silicon hydride species.
