Improving the performance of palladium-catalysed telomerization of 1,3-butadiene by metallocene-based phosphine ligand

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

Zwitterionic phosphonium ligands: Synthesis, characterization and application in telomerization of 1,3-butadiene

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

Telomerization of 1,3-butadiene with highly substituted alcohols using Pd/NHC-catalysts — Structure-reactivity-relationship of the O-nucleophile

Catalytic telomerization of 1,3-butadiene with alcohols is a catalytic reaction and an effective tool to synthesize 2,7-octadienyl ethers with different characteristics depending on the alcoholic substrate. While Pd/phosphine type catalysts were studied i

Comparison between phosphine and NHC-modified Pd catalysts in the telomerization of butadiene with methanol - A kinetic study combined with model-based experimental analysis

The telomerization of butadiene with methanol was investigated in the presence of different palladium catalysts modified either with triphenylphosphine (TPP) or 1,3-dimesityl-imidazol-2-ylidene (IMes) ligand. When pure butadiene was used as substrate, a m

PROCESS FOR TELOMERIZATION OF BUTADIENE USING A MONO-ORTHOALKOXY SUBSTITUTED CATALYST

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.

Large P-P distance diphosphines and their monophosphine analogues as ligands in the palladium-catalyzed telomerization of 1,3-butadiene and methanol

The potential of diphosphines based on a dibenzodioxocin or benzofurobenzofuran backbone possessing large P-P distances was studied for the selective telomerization of 1,3-butadiene with methanol under commercially relevant process conditions to obtain 1-

Telomerisation of buta-1,3-diene and methanol: Superiority of chromanyl-type phosphines in the dow process for the industrial production of 1-MOD

Butadiene and methanol were telomerised in the presence of palladium catalysts with ligands containing 8-diphenylphosphinochromane-like substituents at phosphorus. MonoXantphos and monoSPANphos afforded the most active, stable and selective catalysts known to date under commercially relevant production conditions for 1-methoxyocta-2,7-diene, the precursor to oct-1-ene.

Efficient bulky phosphines for the selective telomerization of 1,3-butadiene with methanol

A series of bulky phosphines containing substituted biphenyl, 2-methylnaphthyl, or 2,7-di-tert-butyl-9,9-dimethylxanthene moiety were prepared. They were used in the preparation of new monophosphine-palladium(0)- dvds complexes, which were employed as catalysts for the selective telomerization of 1,3-butadiene with methanol to obtain 1-methoxyocta-2,7-diene (1-MOD), the key intermediate in the Dow 1-octene process. Several ligands showed improved selectivity and yield compared to that of the benchmark ligand PPh3. Especially 2,7-di-tert-butyl-9,9-dimethylxanthen-4-yl- diphenylphosphine (4, mono-xantphos ) stands out as an excellent ligand in terms of yield, selectivity, and stability.
