A hydrosilylation iron catalyst prepared from a two-electron ligand (L) and a mononuclear, binuclear, or trinuclear complex of iron indicated by formula (1), Fe having bonds with carbon atoms included in X and the total number of Fe-carbon bonds being 2-10. As a result of using iron, the hydrosilylation iron catalyst is advantageous from a cost perspective as well as being easily synthesized. Hydrosilylation reactions can be promoted under mild conditions by using this catalyst.

A process and composition for the hydrosilylation of an unsaturated compound comprising reacting (a) a silyl hydride with (b) an unsaturated compound in the presence of (c) a platinum compound and (d) a cyclodiene, with the proviso that when the unsaturated compound is a terminal alkyne, the silyl hydride is other than a halosilane. The process and composition optionally comprise an inhibitor (e). The process and composition may be employed to form a variety of hydrosilylation products.

A process for the hydrosilylation of an unsaturated compound comprising reacting (a) a silyl hydride with (b) an unsaturated compound in the presence of (c) a platinum based hydrosilylation catalyst comprising a platinum-diene complex with chelating anions. The use of the present catalysts in the process provides silylated products in good yields and allows for using lower platinum loadings than conventional catalysts, reduced cycle times, and may reduce yellowing in the product.

The present invention is directed to a mild, efficient, and general direct C(sp.sup.2)-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 CH 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.

A ligand component is formed according to formula (1):R.sup.1.sub.2PXNC(R.sup.2)Y, wherein R.sup.1 is Ph or Cyc or a C.sub.1-C.sub.20 substituted or unsubstituted ailkyl group; each Ph is a substituted or unsubstituted phenyl group; each Cyc is a substituted or unsubstituted cycloalkyl group; X is an unsubstituted arylene or a C.sub.2-C.sub.3 substituted or unsubstituted alkylene; R.sup.2 is H, methyl or Ph; and Y N is pyridyl, 6-phenylpyridyl or 6-methylpyridyl; with the proviso that when X is a C.sub.2 substituted or unsubstituted alkylene and Y is pyridyl, R.sup.2 is methyl or Ph.
