| 摘要 |
The present invention relates to (2-arylpropyl)silanes represented by the formula (III) and a process for the preparation of the formula (III) by the Friedel-Crafts alkylation of various substituted aromatic compounds represented by the formula (I) with allylchlorosilanes as represented by the formula (II) in the presence of Lewis acid catalysts such as aluminum chloride. RArR' (I) <IMAGE> (II) <IMAGE> (III) In the formulas (I) and (III), R and R' represent independently hydrogen, alkyl (C1-C4), phenoxy, fluoro, chloro, bromo, mercapto, mercaptomethyl and Ar represents phenyl ring, naphthalene ring, or biphenyl ring. X1, X2, and X3 represent hydrogen or chloro group; and wherein formula (III) according to the present invention specifically excludes the compounds of the general formula (III) in which X1, X2 and X3 are all chloro group, and R is hydrogen and R' is hydrogen, chloro or bromo, and X1 is hydrogen and X2 and X3 are all chloro, and R and R' are all hydrogen.
