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).
本发明涉及具有芴基取代的有机硅烷化合物,其化学式为I,并且涉及通过在铝氯化物等路易斯酸催化剂的存在下将化学式II表示的取代联苯与化学式III表示的(二氯代烷基)硅烷反应制备它们的制备方法:##STR1## (其中m为0或1,n为0、1或2。y1和y2代表氢、溴、苯基,它们可以相同也可以不同。R代表氢或甲基基团。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)。
