The present invention relates to fluorenyl substituted organosilanes represented by the formula I and preparation methods thereof by reacting substituted biphenyls represented by the formul II with (dichloroalkyl)silanes represented by the formul III in the presence of Lewis acid catalysts such as aluminum chloride: ##STR1## (wherein m is 0 or 1 and n is 0, 1, or 2. y1 and y2 represent hydrogen, bromo, phenyl and they can be same or different. R represents hydrogen or methyl group. R.sub.j.sup.- can be dichloromethyl, 2,2-dichloroethyl, 3,3-dichloropropyl, 1,2-dichloroethyl, 2,3-dichloropropyl, 2,3-dichlorobutyl).
本发明涉及一种由式I表示的芴基取代有机硅烷化合物及其制备方法,通过在铝氯化物等Lewis酸催化剂存在下,将式II表示的取代联苯与式III表示的(二氯代烷基)硅烷在反应,制备上述化合物:##STR1## (其中,m为0或1,n为0、1或2。y1和y2表示氢、溴、苯基,它们可以相同也可以不同。R表示氢或甲基基团。R.sub.j.sup.-可以是二氯甲基、2,2-二氯乙基、3,3-二氯丙基、1,2-二氯乙基、2,3-二氯丙基、2,3-二氯丁基)。
