摘要: 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.

摘要: The present invention is directed to a mild, efficient, and general direct C(sp)-H bond silylation. Various embodiments includes methods, each method comprising or consisting essentially of contacting at least one organic substrate comprising a terminal alkynyl C—H bond, with a mixture of at least one organosilane and an alkali metal hydroxide, alkali metal alkoxide, or alkali metal hydride under conditions sufficient to form a silylated terminal alkynyl moiety. The methods are operable in the presence or substantially absence of transition-metal compounds. The systems associated with these methods are also disclosed.

摘要: The present invention is directed to a mild, efficient, and general direct C(sp2)-H bond silylation of terminal olefins. Various embodiments includes methods, each method comprising or consisting essentially of contacting at least one organic substrate comprising a terminal olefinic C—H bond, with a mixture of at least one organosilane, organosilane, or mixture thereof and an alkali metal alkoxide or alkali metal hydroxide, such that the contacting results in the formation of a silylated olefinic product. The systems associated with these methods are also disclosed.
