Transition metal-catalysed rearrangement of allyl but-3-enoate to hepta-2,6-dienoic or hepta-3,6-dienoic acids
Abstract
The rearrangement of allyl but-3-enoate to heptadienoic acids is catalysed by nickel and rhodium complexes in the presence of phosphorus-containing ligands and can be driven towards either the 2,6- or the 3,6-isomers through selective hydrogen abstraction.
