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.

Una composicin de catalizador a base de fosfina adecuada para la telomerizacin de butadieno para producir 1-octeno incluye paladio y uno de una clase denuevos ligandos de fosfina caracterizado por dos anillos fenilo potencialmente funcionalizados y un tercer grupo fenilo que tiene una funcionalidad alcoxi en una de las posiciones orto, que es parte de un anillo de 5 6 miembros entre esta posicin orto y la posicin meta adyacente, no siendo este anillo parte de un segundo grupo arilo. Los catalizadores que incluyen esta clase de ligandos de fosfina pueden presentar mayor actividad y selectividad, y se pueden usar a menores temperaturas que muchos otros catalizadores de ligandos de fosfina, reduciendo costes. Tambin 10 se reduce la precipitacin de paladio.
