Abstract
The present invention relates to a process for preparing (2-arylpropyl)alkylsilanes represented by the formula III by reacting (2-arylpropyl)silanes represented by the formula I with olefin compounds represented by the formula II in the presence of hydrosilation catalysts such as chloroplatanic acid, platinum on silica, tributylamine and Pd, Rh, Ni metals. ##STR1## Olefin compounds(cyclohexene or CH.sub.2 =CH--R.sup.3) (II) ##STR2## In the formulas (I) and (III), R.sup.1 and R.sup.2 represent independently hydrogen, alkyl(C.sub.1 -C.sub.4), fluoro, chloro or bromo; and Ar represents phenyl ring, naphthalene ring, or biphenyl ring. X represents hydrogen or chloro group. In the formula (III), R represents --(CH.sub.2 CH.sub.2)--R.sup.3, sec-butyl, or cyclohexyl wherein R.sup.3 =Ph, CH.sub.2 Cl, C.sub.n H.sub.2n CH.sub.3 (n=0-15), CH.sub.2 Si(Me).sub.m Cl.sub.3-m (m=O-3), (CH.sub.2).sub.2 Si(Me).sub.m (OMe).sub.3-m (m=O-3), (CH.sub.2).sub.3 Si(Me).sub.m (OMe).sub.3-m (m=O-3), Si(Me).sub.m Cl.sub.3-m (m=0-3), CF.sub.3, CN, CH.sub.2 CN, ##STR3## CH.dbd.CH.sub.2, (CH.sub.2 ).sub.4 CH.dbd.CH.sub.2, ##STR4## or Ph--CH.sub.2 Cl.
