By replacing one planar phenyl group of PPh3 with bulkier ferrocenyl or ruthenocenyl group, the performance of resulted metallocene-based phosphine ligand in the telomerization of 1,3-butadiene with methanol has been largely elevated compared t

Novel zwitterionic phosphonium alkylsulfonate ligands are chemoselectively synthesized from N-heterocyclic phosphines and cyclic sulfones in one step in good to excellent yields. Their in situ generated palladium complexes showed high productivity in the
PROCESS FOR TELOMERIZATION OF BUTADIENE USING A MONO-ORTHOALKOXY SUBSTITUTED CATALYST

Page/Page column 14-16, (2012/07/13)
A process for the telomerization of butadiene comprises reacting 1,3-butadiene and an alkanol, in the presence of a catalyst promoter and an alkoxydimerization catalyst comprising a Group VIII transition metal and a triarylphosphine ligand, which includes one phenyl that is mono-ortho-alkoxy substituted and at least one other phenyl including at least one substituent that withdraws electrons from the phosphorus atom. The product includes an alkoxy-substituted octadiene, which may then be used to produce 1-octene. The catalyst shows improved stability, activity and selectivity toward the alkoxy-substituted octadiene.
