The Grubbs' ruthenium-carbene complexes, RuCl 2 (=CHPh)(PR 3 ) 2 , mediate the Kharasch addition of CCl 4 across olefins, and the controlled atom transfer radical polymerisation of vinyl monomers with high yields and selectivities which markedly depend on the phosphine ligands of the complex (R=phenyl, cyclopentyl, and cyclohexyl).
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 olefins.
