(57) [Summary] (Modifications) [PROBLEMS] Hydrosilylation to increase the rate of formation of β-adduct in the addition reaction to a double bond and to increase the rate of formation of a main product when by-products are formed Provide a way. A c) compounds of the general formula HSiR 13 3 and d) Hydrosilylation reaction of the unsaturated hydrocarbon group-containing compound, a) General formula HR 2 Si—R 1 —R 2 —Z (R 1 is —O—, —NR 3 —; R 2 is —CR 7 R 8 —; Z is —C≡CHR 9 , -R 10 C = CHR 9, -R 11 HCOR 12, -C 4 H 3 O R 3 , R 9 to R 11 are H, C1-8 hydrocarbon group or Si R 4 R 5 R 6 (R 4 to R 5 are H or a C1-3 alkyl group); R 12 is a C1-3 divalent hydrocarbon group; R 13 is a C1 To 18 hydrocarbon groups, C1 to 18 halogenated hydrocarbon groups, C1 to 6 alkoxy groups, C6 to 10 aryloxy groups, Cl, siloxy groups or siloxanoxy groups. The reaction is carried out in the presence of both the silicon compound of (a) and b) a platinum catalyst. |
