The present invention relates to a process for preparing tris(silyl)alkanes comprising directly reaction a mixture of organic compounds having a trichloromethyl group represented by formula I and hydrogen chloride or alkyl chlorides represented by formula II, with metallic silicon to give the tris(silyl)alkanes represented by formula III, IV, V and VI: ##STR1## wherein R represent independently hydrogen or methyl and R' represents hydrogen, alkyl(C.sub.1 -C.sub.4), or CH.sub.2 CH.sub.2 Cl.
                            本发明涉及一种制备三(
硅烷基)烷的方法,包括将式I表示的具有三
氯甲基基团的有机化合物混合物与
氯化氢或式II表示的烷基
氯化物直接反应,然后与
金属
硅反应,得到式III、IV、V和VI表示的三(
硅烷基)烷:其中,R独立地表示氢或甲基,R'表示氢、烷基(C.sub.1-C.sub.4)或CH.sub.2 CH.sub.2 Cl。
