In the palladium catalyzed alkoxycarbonylation of cinnamyl chloride two mechanisms play a role. An associative mechanism was observed at low pressure, while an insertion mechanism was observed at high pressure or when an excess of ligand was used. Several putative intermediates of the catalytic alkoxycarbonylation have been synthesized and characterized, such as 5c of which an X-ray crystal structure was obtained.

The μ-η3-allenyl/propargyldipalladium complexes were synthesized by the reaction of the corresponding η1-allenyl- or η1-propargylpalladium complexes with Pd2(dba)3. The X-ray diffraction analysis indi

Regioselectivity in the palladium-catalysed allylic alkylation of 1-arylprop-2-enyl acetates [ArCH(OAc)CH=CH2] or (E)-3-phenylprop-2-enyI acetate (PhCH=CHCH2OAc) with sodium enolates of soft carbon nucleophiles is controlled by addition of a catalytic amount of lithium iodide to give lienar products [(E)-ArCH=CHCH2Nu] exclusively; their branch isomers [ArCH(Nu)CH=CH2] were not detected.
