Abstract

The reaction of methylenecyclopropane and 1-cyclopropylidene pentane with iodobenzene or 2-bromopropene and a delocalized anion (issued from malonate or from a β-sulfonyl ester) in the presence of catalytic amounts of a palladium (O) complex leads to conjugated dienes or to styrenes 5, 6, 8 or 9. These compounds are probably issued of the capture of a II- allylic complex which results from the rearrangement of the initially formed α- ...
