Norbornadiene as an Efficient Hydrogen Scavenger for the Palladium-Catalyzed Conversion of Hydrosilanes to Alkoxysilanes
摘要:
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.

Intrachain energy transfer in silylene-spaced alternating donor–acceptor divinylarene copolymers
Silylene-spaced donor-acceptor divinylarenecopolymers are synthesized by hydrosilylation of bisalkynes 7 with bisvinylsilanes 3; efficient intrachain energy transfer between donor-acceptor chromophores is observed.
