    摘要: An N-tert-butyldialkylsilylmaleimide represented by the following general formula: ##STR1## wherein R's represent C.sub.1 to C.sub.5 alkyl groups which may be the same or different and a method of producing the compound. Said N-tert-butyldialkylsilylmaleimide is useful as a silylating agent, which does not produce hydrogen chloride or the like as a by-product and therefore does not require to use a neutralizing agent additionally. Further this compound is useful as a compound which provides a maleimido group.

    摘要: 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.
