摘要： Several thexyl trialkoxy silanes as a novel class of organosilicon compounds were synthesized by the reaction of dehydrochlorination condensation between thexyl trichlorosilane and an alcohol, e.g., methyl, ethyl, isopropyl and isobutyl alcohols, and characterized by the analytical data. These compounds are useful as an intermediate in the synthetic preparation of other organosilicon compounds, starting material of various silicones, surface-treatment agent of inorganic materials and additive in complex catalysts.

摘要： Thexyl (C.sub.1 -C.sub.4) alkyl dialkoxy silanes are proposed as a class of novel organosilicon compounds such as thexyl methyl dimethoxy silane and thexyl n-butyl dimethoxy silane. These silane compounds can be synthesized by several different routes. For example, thexyl methyl dimethoxy silane is prepared starting from methyl phenyl chlorosilane which is subjected to the hydrosilation reaction with 2,3-dimethyl-2-butene to introduce a thexyl group and the compound is converted by the reaction with hydrogen chloride into thexyl methyl dichlorosilane which is methoxylated by the reaction with methyl alcohol.

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.

摘要： A silylating agent comprising an N-(trialkylsilyl)benzanilide having the following general formula: ##STR1## wherein R.sup.1 is a lower alkyl group. This agent is reacted with a secondary amine to produce an N,N-dialkylaminotrialkylsilane. This process is free of formation of amine hydrochlorides as by-products. Therefore, the problem associated with disposal of such amine hydrochlorides and the problem of limitations on the use of the silane compound product due to mixing of such amine hydrochlorides can be obviated effectively.
