Abstract:
1. A process for selectively producing a monosilylated product from a composition containing a silyl hydride and a polyunsaturated compound comprising contacting the composition with a complex of Formula (I), Formula (II) or Formula (III) to cause the silyl hydride to react with the polyunsaturated compound such that hydrosilylation occurs selectively at one unsaturated group of the unsaturated compound thereby producing the mono-hydrosilylated product, wherein the polyunsaturated compound is represented by Formula (IV) or Formula (V) wherein E E each occurrence of R each occurrence of α, β and γ is independently an integer, wherein α is 2 to 6; β is 0 to 6; and γ is 0 to 4; wherein Formula (I), Formula (II) and Formula (III) are: wherein: G is Mn, Fe, Ni, or Co; each occurrence of R each occurrence R optionally any two of R each of L wherein each occurrence of R each occurrence of R optionally any two of R each occurrence of R each occurrence of R each X is independently C1-C18 alkyl, C1-C18 substituted alkyl, aryl, or substituted aryl, wherein X optionally contains at least one heteroatom; and wherein the molar ratio of the Si—H functional groups in the silyl hydride to the alkenyl functional groups in the unsaturated compound is between about (0.5:α) and about (1.1:α).
