    Abstract: 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.

    Abstract: The present invention is directed to methods of forming olefins, especially linear alpha olefins from fatty acids or anhydrides, each method comprising: contacting an amount of precursor carboxylic acid anhydride with a palladium catalyst comprising a bidentate bis-phosphine ligand in a reaction mixture so as to form an olefin in a product with the concomittant formation and removal of CO and water from the reaction mixture, either directly or indirectly, wherein the reaction mixture is maintained with a sub-stoichiometric excess of a sacrificial carboxylic acid anhydride, an organic acid, or both, said sub-stoichiometric excess being relative to the amount of the precursor carboxylic acid anhydride. The precursor carboxylic acid anhydride may be added to the reaction mixture directly or formed in situ by the reaction between at least one precursor carboxylic acid with a stoichiometric amount of the sacrificial acid anhydride.
