description 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. (I) Olefin compounds(cyclohexene or CH2=CH-R3) (II) (III) In the formulas (I) and (III), R1 and R2 represent independently hydrogen, alkyl(C1-C4), 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 -(CH2CH2)-R3, sec-butyl, or cyclohexyl wherein R3=Ph, CH2Cl, CnH2nCH3 (n=0-15), CH2Si(Me)mCl3-m (m=O-3), (CH2)2Si(Me)m (OMe)3-m (m=O-3), (CH2)3Si(Me)m (OMe)3-m (m=O-3), Si(Me)mCl3-m (m=0-3), CF3, CN, CH2CN, CH=CH2, (CH2 )4CH=CH2, or Ph-CH2Cl.
