Sequential Reactions of Trimethylstannyl Anions with Vinyl Chlorides and
Dichlorides by the SRN1 Mechanism Followed by Palladium-Catalyzed
04- 185 Cross-Coupling
Processes. — To obtain good yields of vinylstannanes from the reaction of Me3Sn- with vinyl chlorides, the reactions are performed either in the dark or
under UV irradiation, depending on the vinyl chlorides used. The coupling reactions of
the resulting stannanes with aryl iodides give access to triarylolefins. These olefins can
be also obtained by a one-pot method combining the above two steps. — (CORSICO,
