The di-tert-butyl peroxide-initiated reactions of triethyl- and tri-n-propylsilane with bis-(vinyldim ethylsilyl) compounds, CH2=CH(CH3)2SiXSi(CH3)2CH=CH2(X-O,CH2, NH,NCH3 and NSiMe3) resulted in hydrosilylation-cyclization to give mixtures of trialkylsilylm ethyl-substituted disilacyclohexanes and trialkylsilylm ethyl-substituted disilacyclopentanes. The ratio of six-membered to five-membered ring products obtained is dependent on the linking group X and decreased in the order X=O>CH2>NH>NCH3. For X = NSiMe3 only a mixture of the cis and trans isomers of the five-membered ring product was obtained.
