1,3-Bis(3-butylimidazolium-1-yl)benzene diiodide (1) was reacted with Li(2,2,6,6-tetramethylpiperidine) yielding the free bis-carbene, 1,3-bis(3-butylimidazol-2-ylidene-1-yl)benzene (3), which has been spectroscopically characterized. Combining the free b

1-Tri(phenyl, methyl)silyl-1-alkenes of the general formula RCH=CHSiMe3-nPhn (where n = 1-3, R = CmH2m+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-alkenes (predominantly E-isomers) in high yields of up to 90percent (in turn of vinylsilane).The products were identified by spectroscopic (IR, Raman, 1H, 13C NMR and GC-MS) methods.
