✦ Synopsis

In

the cross-metathesis reaction of tri(methyl, ethoxy)vinylsilanes with propene and/or 1-butene catalyzed by RuCl 2 (PPh 3 ) 3 activated in benzene at 115-130 °C, a series of l-alkenylsilanes of general formula CH 3 (CH 2 ) m CH = CHSiMe 3 Ϫ n (OEt) n , where m = 0, 1, and n = 0-3 (1-silyl-1-alkenes), as well as of formula CH 2 = C(Me)SiMe 3 Ϫ n (OEt) n , where n = 1, 2 (2-silyl-1-alkenes), were obtained. Additional products determined were allysilanes of general formula CH 2 = CHCH 2 SiMe 3 Ϫ n (OEt) n and CH 3 CH = CHCH 2 SiMe 3 Ϫ n (OEt) n , where n = 1-3.
