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.

A neutral or cationic mononuclear ruthenium divalent complex represented by formula (1) can actualize exceptional catalytic activity in at least one reaction among a hydrosilylation reaction, hydrogenation reaction, and carbonyl compound reduction reaction.

The present invention relates to hydrosilylation reactions between a monosubstituted alkene compound and a compound comprising at least one hydrogen atom bonded to a silicon atom. More specifically, the invention relates to a process for the hydrosilylation of an unsaturated compound (A) that comprises at least one monosubstituted alkene function with a compound (B) that comprises at least one hydrosilane function, said process comprising the step of exposing said unsaturated compound (A) and said compound (B) to irradiation in the presence of a photocatalyst (C) consisting of a manganese carbonyl. This hydrosilylation reaction between an alkene compound and a compound comprising at least one hydrogen atom bonded to a silicon atom makes it possible, in particular, to cure silicone compositions by crosslinking.

Provided is a catalyst which comprises a compound represented by formula (1) and which exhibits activity for at least one type of reaction selected from among hydrosilylation reaction or hydrogenation reaction with respect to an aliphatic unsaturated bond and hydrosilane reduction reaction with respect to a carbon-oxygen unsaturated bond or a carbon-nitrogen unsaturated bond. Formula (1): M.sub.n(L.sub.m) {M represents Fe, Co, or Ni having an oxidation number of 0, L represents an isocyanide ligand represented by formula (2), n denotes an integer of 1-8, and m denotes an integer of 2-12. Formula (2): (CN).sub.xR.sup.1 (R.sup.1 represents a mono- to trivalent-organic group having 1-30 carbon atoms, optionally being substituted by a halogen atom, and optionally having interposed therein one or more atoms selected from among O, N, S, and Si; and x denotes an integer of 1-3)}.

Provided is a fluorene compound having a sulfonic acid ester structure and an allyl group, the compound being represented by formula (1).
