<P>PROBLEM TO BE SOLVED: To provide a catalyst which enables synthesis of organosilicon compounds having a carbon-carbon double bond by reacting a siloxane containing an unsaturated bond with a ≡Si-H group in the presence of it. <P>SOLUTION: The catalyst for reactions of introducing a silicon into an unsaturated carbon of a siloxane having an aliphatic or alicyclic unsaturated bond is a transition metal complex compound of formula (1) X<SB>t</SB>-M-R<SP>1</SP><SB>s</SB>(Y<SB>u</SB>) (wherein, M is a transition metal atom; R<SP>1</SP>is H, alkyl, aryl or SiR<SB>3</SB>; R is H, monovalent hydrocarbon, alkoxy, halogen or a siloxane residue; X is a cyclic group having an aliphatic unsaturated group, trispyrazolyl borate, tetrafluoroborate, hexafluorophosphate, porphin or phthalocyanine; Y is ammonia, carbonyl, an oxygen atom, oxygen molecule, amine, phosphine or a phosphite; 0<s≤3; 0≤t<2; 0≤u≤12; and s and t are such numbers as to give the oxidation number of the transition metal atom of II or IV). <P>COPYRIGHT: (C)2011,JPO&INPIT |
