STERIC EFFECTS IN HYDROSILYLATION OF STYRENE

Hydrosilylation of styrene, 2-phenyl-1-propene, trans-1-phenyl-1-propene by (CH3)R2SiH (R=C2H5, i-C3H7, i-C4H9) and R3'SiH (R'=i-C3H7, t-C4H9) in the presence of 3> (I), 2> (II) and H2PtCl6 as catalysts has been studied.The reaction of styrene with (CH3)R2SiH catalysed by complex I in benzene leads to α- and β-adduct as well as to a substitution product.Analogous addition of (i-C3H7)3SiH catalysed by complexes I and II produces selectively trans-1-triisopropylsilyl-2-phenylethylene.Reaction of 2-phenyl-1-propene with CH3(C2H5)2SiH gives 1-diethylmethylsilyl-2-phenylpropane, 1-diethylmethylsilyl-2-phenyl-2-propene and 1-diethylmethylsilyl-2-phenyl-1-propene.Hydrosilylation of trans-1-phenyl-1-propene by diethylmethylsilane catalysed by complex I gave 1-diethylmethylsilyl-2-phenylpropane and 3-diethylmethylsilyl-1-phenylpropane.Conversion of 2-phenyl-1-propene and trans-1-phenyl-1-propene in their reaction with diethylmethylsilane catalysed by complex I was found to be much lower compared to the reaction with styrene and attained maximum at 60 deg C.The selectivity and rates of above reactions can be influenced by the presence of air oxygen.
