A silylation of vinyliodonium salts using zinc-based silicon reagents as nucleophiles is reported. This cross-coupling is catalyzed by copper, and vinylsilanes are obtained in high yield likely following a Cu(I)/Cu(III) reaction mechanism. The procedure i
THE ASYMMETRIC HYDROBORATION OF SIMPLE ALKENYLSILANES: CHIRAL α-SILYLALKYL-BORANES AND ALCOHOLS

The detailed study of the asymmetric hydroboration of various vinylsilanes with monoisopinocampheylborane (IPCBH2) is presented.In all cases, β substitution on the vinylsilane gives monomeric dialkylborane adducts with the boryl group α to the silicon.These studies shown that the larger the groups on silicon are, the more positive the influence on the enatioselectivity of the process.Moderate asymmetric induction (24-40percent) is observed only for vinyl silanes wich contain a substituent trans to the silicon.A model for the asymmetric hydroboration of alkenes with this reagent is proposed.The complete charactarization of the borane intermediates was achieved employing NMR (11B, 13C, 1H, 29Si).
NEW SYNTHESES OF VINYLSILANES AND ALLYLSILANES BY CROSS-COUPLING OF (R3Si)3MnMgMe WITH ALKENYL AND ALLYLIC COMPOUNDS

The reaction of alkenyl halides, alkenyl sulfides, and enol phosphates with (R3Si)3MnMgMe provides vinylsilanes in good yields.The method is also applicable to the allylsilane synthesis from allylic sulfides and ethers.
