    摘要: In an improved process for telomerizing butadiene, contact butadiene and an organic hydroxy compound represented by formula ROH (I), wherein R is a substituted or unsubstituted C1-C20-hydrocarbyl and the organic hydroxy compound is not glycerol, in a reaction fluid in the presence of a palladium catalyst and a phosphine ligand represented by formula PAr3 (II), wherein each Ar is independently a substituted or unsubstituted aryl having a hydrogen atom on at least one ortho position, at least two Ar groups are ortho-hydrocarbyloxyl substituted aryls. The phosphine ligand has a total of two (2), three (3), four (4), five (5), or six (6) substituted or unsubstituted C1-C20-hydrocarbyloxyls, and optionally, any two adjacent substituents on an Ar group can be bonded to form a 5- to 7-membered ring.

    摘要: 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 cyclized 5- or 6-member alkoxy groups that, together, bridge the two potentially functionalized phenyl rings. In these groups the alkoxy moiety of each is located ortho to at least one functionalizing moiety, if any, on the phenyl rings. 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.

    摘要: 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.
