ABNORMAL PRODUCTS OF PALLADIUM CATALYSED REACTIONS OF (1-BROMOVINYL)TRIMETHYLSILANE
Ennis, David S.,Gilchrist, Thomas L.
, p. 3735 - 3736 (1989)
Coupling reactions of (1-bromovinyl)trimethylsilane (1) with organozinc bromides catalyzed by tetrakis(triphenylphosphine)palldium(0) give not only the expected 1-substituted vinylsilanes (2) but also the isomeric 2-substituted vinylsilanes (3).
