ABSTRACT:
Cyclopentyl trichlorosilane can be efficiently prepared by the hydrosiliaton reaction of trichlorosilane and cyclopentene which can proceed only to a very low extent by the use of conventional platinum catalysts effective in other hydrosilation reactions. Thus, an equimolar mixture of the reactants is heated in the presence of a chlorine-deficient chloroplatinic acid catalyst of a specified chlorine:platinum atomic ratio at a temperature higher than the boiling point of the mixture under normal pressure in a pressurizable vessel so that the desired product can be obtained in a yield of 90% of the theoretical value or higher.
