Co-dimerisation of 1,3-Dienes and Acrylic Esters catalysed by Cationic Allylpalladium Complexes: the Role of Phosphines

Basic phosphines, especially tributylphosphine, when added in 1:1 ratio to cationic allylpalladium complexes, allow the selective co-dimerisation of 1,3-dienes and acrylic esters to linear, unsaturated esters, presumably owing to the inducement of an η3-η1 shift of the allyl ligands by the phosphines.

Ligand effects and nucleophilic addition to (η3-allyl)palladium complexes. A carbon-13 nuclear magnetic resonance study

With the use of acceptor ligands such as phosphines, large downfield 13C shifts may be induced selectively at the more substituted terminus of an unsymmetric (η3-allyl)palladium system. Bidentate ligands with one acceptor and one donor function may induce even greater relative downfield shifts at the more substituted terminus. The observed downfield chemical shifts follow closely the anticipated acceptor properties of the ligands, suggesting that there may be a relation between 13C NMR shifts and relative charge at the η3-allyl termini.
