A palladium-catalyzed mild and efficient method for the alcoholysis of hydrosilanes containing a C=C bond in the presence of norbornadiene (NBD) is reported. The highly strained NBD acts as a hydrogen scavenger, which abstracts the hydrogen produced during the process, protecting the C=C bond from being hydrogenated.

Reaction of β-styrylpentamethyldisilane (1a) with Ru3(CO)12 afforded β-styryltrimethylsilane (2a) with elimination of a dimethylsilylene unit, while under similar conditions α-isomer 1b yielded 2a together with 1a. Studies on these r

The chemical behaviour of sila-2 butadienes, formed as transient intermediates either by thermolysis or by photolysis of various 1-vinylsilacyclobutanes, was studied with respect to hydroxylated compounds of different pKa values.Two mechanisms can explain the nature of the products obtained on the co-thermolysis of the cyclic compounds with phenol, one with 1-silacyclobut-1-ene intermediate and the other involving an allylic silicenium cation.In both hypothetical mechanisms, the 2-silabutadienes behave as a conjugated system since they lead either to cycloaddition or to (1,2)- and (1,4)-electrophilic addition.This evidence for a conjugation phenomenon through a silicon atom is supported by the calculation of the delocalisation energies of butadiene and 2-silabutadiene.
