Download chapter PDF Author information Authors and Affiliations WebStructure of allylpalladium chloride dimer. Transition-metal allyl complexes are coordination complexes with allyl and its derivatives as ligands. Allyl is the radical with the connectivity CH 2 CHCH 2, although as a ligand it is usually viewed as an allyl anion CH 2 =CH−CH 2−, which is usually described as two equivalent resonance structures.
WebA palladium-catalysed aromative benzylic allylation and allenylation of benzyl chlorides with allyl and allenyl pinacolborates is described for the first time. The reactions proceed smoothly in the presence of a bidentate phosphine ligand to afford normal cross-coupling products in good yields.
