Pietraszuk, Cezary,Marciniec, Bogdan,Fischer, Helmut
, p. 7121 - 7124 (2003)
The efficient cross-metathesis of vinylsilanes carrying electron-withdrawing substituents with various olefins is described. High yields and selectivities were obtained when styrene, 1-hexene, and selective functional allyl derivatives were used as the ol

The reactivity of a well defined Rh (I) complex, i.e. Rh(CF 3COO)(NHC)(COD) (1, NHC = 1,3-bis(2,4,6-trimethylphenyl)-3,4,5,6- tetrahydropyrimidin-2-ylidene, COD = η4-cycloocta-1,5-diene) in the hydrosilylation of 1-alkenes, alkynes,
Rh(1,3-bis(2,4,6-trimethylphenyl)-3,4,5,6-tetrahydropyrimidin-2-ylidene) (COD) tetrafluoroborate, an unsymmetrical Rh-homoazallylcarbene: Synthesis, X-ray structure and reactivity in carbonyl arylation and hydrosilylation reactions
Imlinger, Nicolas,Wurst, Klaus,Buchmeiser, Michael R.
, p. 4433 - 4440 (2007/10/03)
The synthesis of novel Rh(1,3-bis(2,4,6-trimethylphenyl)-3,4,5,6- tetrahydropyrimidin-2-ylidene)(COD) tetrafluoroborate (1, COD = η4-1,5-cyclooctadiene) is described. The N-heterocyclic carbene acts as a bidentate ligand with the carbene coordinating to the Rh(I) center and an arene group acting as a homoazallyl ligand. 1 was used in various carbonyl arylation and hydrosilylation reactions allowing the formation of the desired products with unprecedented selectivity and efficiency. Thus, turn-over numbers (TONs) up to 2000 were achieved.
The effect of substituents at silicon on the cross-metathesis of trisubstituted vinylsilanes with olefins
Pietraszuk, Cezary,Fischer, Helmut,Rogalski, Szymon,Marciniec, Bogdan
, p. 5912 - 5921 (2007/10/03)
Efficient cross-metathesis of vinylsilanes, carrying a large spectrum of different substituents at silicon, with various olefins in the presence of the first and second generation Grubbs catalyst and Hoveyda-Grubbs catalyst is described. On the basis of the results of equimolar reactions of vinylsilanes with ruthenium alkylidene complexes and experiments with deuterium-labelled reagents, a general, metallacarbene mechanism for the cross-metathesis of trisubstituted vinylsilanes with olefins has been suggested. Reaction was proved to be a valuable method for synthesis of unsaturated organosilicon derivatives.
Hydrosilylation of alkynes catalyzed by platinum on carbon

Organic halides such as PhI, ArBr, and β-bromostyrene reacted with di- or monochlorovinylsilanes or triethoxyvinylsilane in the presence of triethylamine and palladium catalysts to give β-substituted vinylsilanes in excellent to moderate yields.
The β-Effect: Changing the Ligands on Silicon
Brook, Michael A.,Neuy, Axel
, p. 3609 - 3616 (2007/10/02)
The ability of a silyl group to stabilize a carbocation β to silicon, the β-effect, is directly related to the electron-withdrawing ability of the groups on silicon.This was shown by using the degree of syn addition of bromine to (E)-β-silylstyrenes as a
