    Abstract: A phosphine-based catalyst composition suitable for the telomerization of butadiene to produce 1-octene includes palladium and one of a class of novel phosphine ligands characterized by two potentially functionalized phenyl rings and a third phenyl group having an alkoxy functionality on one of the ortho-positions, which is part of a 5- or 6-membered ring between this ortho position and the adjacent meta position, this ring not being part of a second aryl group. The catalysts including this class of phosphine ligands may exhibit higher catalytic activity and selectivity, and may be used at lower temperatures, than many other phosphine ligand catalysts, reducing costs. Palladium precipitation may also be reduced.
