ADDITION OF ALKYL- AND ARYLPALLADIUM CHLORIDES TO CONJUGATED DIENES

Aryl- and certain alkylpalladium chlorides, prepared in situ from aryl- or alkylmercury or -tin compounds and lithium palladium chloride, react readily with conjugated dienes to form 1-arylmethyl or l-alkyl-π-allylpalladium chloride dimers, in low to moderate yields. A catalytic synthesis of arylbutenyl acetates from a conjugated diene, an arylmercuric salt, and lead tetraacetate with a catalytic amount of palladium acetate is also reported. © 1968, American Chemical Society.
