Abstract 1-Tri (phenyl, methyl) silyl-1-alkenes of the general formula RCH CHSiMe 3− n Ph n (where n= 1-3, R= C m H 2m+ 1, m= 5, 6, 8, 10, and 12; Ph) have been prepared by a novel method, viz. by a very effective cross-metathesis of vinyltri (phenyl, methyl) silanes with 1-alkenes and styrene catalyzed by ruthenium and rhodium complexes. A tenfold excess of 1-alkene in the reaction mixture gave stereospecific 1-tri (phenyl, methyl) silyl-1- ...
