Organosilicon compounds are made by reacting together a silicon compound containing a silicon-bonded hydrogen atom and an unsaturated compound in the presence of a complex of a platinous salt and an olefin. The silicon reactant may be a halogenosilane, organohalogenosilane, polysilane, polysiloxane or polysilcarbane, in which the organic radicals may be alkyl, alkenyl, aryl or haloaryl radicals, but must contain at least 1 Si atom having at least 1 and not more than 2 H atoms bonded thereto, e.g. methyldichlorosilane, dimethylchlorosilane, trichlorosilane, diphenylsilane, methylphenylchlorosilane, 1:4-bis(dimethylsilyl) methylhydrogenpolysiloxanes and siloxanes containing both -Si(CH3)O-and -Si(CH3H,O- units. The organic reactant can be any unsaturated compound except aliphatic amines, aldehydic compounds and compounds having a cyano group on an unsaturated C atom, and may be a purely organic compound or an organosilicon compound, numerous examples of which are given. The silicon compound may contain both the H and the unsaturated radical. The catalysts specified are complexes of ethylene, propylene, butylene, cyclohexene and styrene with platinous chloride. The reaction is preferably effected with the range of 10 DEG to 150 DEG C. at normal or super-atmospheric pressure. In examples, polymers were made (1, 2 and 7) by polymerizing methylphenylvinylsilane in presence of the platinum complexes, or (3, 10, 11 and 12) by reacting siloxanes containing Si-H with unsaturated compounds; and addition products were made by the above process from (4) methyldichlorosilane and vinylacetate; (5, 13) 1.3.5.7-tetramethylcyclo-tetrasiloxane and styrene or methylmethacrylate; (6, 8) methyldichlorosilane and allylcyanide or commercial diisobutylene; (9) trichlorosilane and commercial diisobutylene; and (14) methylphenyl-vinylchlorosilane and diphenylchlorosilane. |
