Nickel(II) dibromide complexes bearing bis(benzimidazolyl)amine and Bis(benzimidazolyl)pyridine ligands for ethylene oligomerizations

A series of bis(benzimidazolyl)amine and bis(benzimidazolyl)pyridine ligands and their respective nickel(II) dibromide complexes were synthesized and fully characterized. After activation of the nickel complexes with ethylaluminum sesquichloride showed productivity in excess of 106 (g-oligomer)(mol-Ni)-1h-1bar-1 towards ethylene oligomerization, producing butenes as major products. The bis(benzimidazolyl) pyridine nickel complexes showed higher activity and dimerization selectivity than corresponding bis(benzimidazolyl)amine nickel complexes.

Synthesis of a new class of 1,4-bis(diphenylphosphino)-1,3-butadiene bridged diphosphine, NUPHOS, via zirconium-mediated reductive coupling of alkynes and diynes: Applications in palladium-catalyzed cross-coupling reactions

The synthesis of a new class of 1,4-bis(diphenylphosphino)-1,3-butadiene was discussed. Catalyst mixtures based on 1,2,3,4-Ph4-NUPHOS were found to be superior to those based on BINAP, with activities of 6900 and 260 (mol of product) (mol of palladium)-1h-1 respectively. The applications in palladium catalyzed cross-coupling reactions were also discussed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 95464-05-4, you can also check out more blogs about95464-05-4

A comparative study of bithiophene and thienothiophene based polymers for organic field-effect transistor applications

2,2?-Bithiophene and thieno[3,2-b]thiophene were polymerized separately with bis(2,3-dialkylthienyl)benzo[1,2-b:4,5-b?]dithiophene by Stille coupling reactions to afford new conjugated polymer PBDTT-2T and PBDTT-TT. The polymers showed band gaps about 1.90?eV and the highest occupied molecular orbital (HOMO) energy levels below ?5.20?eV. The PBDTT-2T and PBDTT-TT achieved hole mobilities of 0.035 and 0.008?cm2?V?1?s?1 in top-contact/bottom-gate organic field-effect transistor devices. The investigation of thin-film microstructures and morphologies showed that PBDTT-2T thin films had more uniform surface and better crystalline quality than PBDTT-TT did.

Pinpoint-fluorinated phenanthrene synthesis based on C-F bond activation of difluoroalkenes Dedicated to Prof. Veronique Gouverneur on the occasion of her receipt of the 2014 ACS Award for Creative Work in Fluorine Chemistry.

Treatment with a cationic palladium(II) catalyst promoted the Friedel-Crafts-type cyclization of 1,1-difluoro-1-alkenes bearing a biphenyl skeleton to afford regioselectively fluorinated (pinpoint-fluorinated) phenanthrenes via C-F bond activation. The obtained pinpoint-fluorinated phenanthrenes were observed to be organized by pi-pi and C-H?F interactions to exhibit columnar and layer structures in the solid state.

Triorganylphosphane-modified palladium(0) compounds catalyze the codimerisation of methylenecyclopropane (1) with methyl acrylate, methyl trans-crotonate or trans-cinnamate to give the methylenecyclopentanecarboxylic esters 3, 4, 5; diethyl fumarate or dimethyl maleate and 1 lead to the methylenecyclopentanedicarbonic esters 12.With diethyl maleate besides cis/trans-12b also oligomers containing two mols of 1 and one (cis/trans-14) or two mols of the diester (cis/trans-15) are formed.

Regio- and Stereoselective Synthesis of Functionalized Dihydropyridines, Pyridines, and 2H-Pyrans: Heck Coupling of Monocyclopropanated Heterocycles

A palladium-catalyzed coupling between aryl halides and monocyclopropanated pyrroles or furans has been developed, leading to valuable six-membered N- and O-heterocycles. As the key step, a selective cleavage of the non-activated endocyclic C?C bond of the 2-heterobicyclo-[3.1.0]hexane framework is achieved. The developed method offers access to highly functionalized piperidines, pyridines, and pyrans that are challenging to access by traditional methods.

Suzuki-Miyaura homocoupling of naphthyl triflates using bis(pinacolato)diboron: Approaches to the biaryl skeleton of crisamicin A

Homocoupling of naphthyl triflates 27, 16, 17 to the respective binaphthyls 28, 31 and 35 has been achieved in a one-pot procedure using bis(pinacolato)diboron and PdCl2(dppf). Use of potassium acetate as the base provides access to the initial naphthylboronate intermediates whereas the stronger base potassium phosphate is required in order to promote subsequent coupling of the naphthylboronate with a second equivalent of the naphthyl triflate. Attempts to convert binaphthyl 35 into bis-acetylnaphthalene 14, a key intermediate for the synthesis of the dimeric pyranonaphthoquinone antibiotic crisamicin A 2, via double Fries rearrangement of bis-acetate 37 derived from binaphthyl 35, were unsuccessful. Attempts to introduce the acetyl groups at C-7 and C-7? on bis-acetylnaphthalene 14 via Fries rearrangement of the monomeric precursors 21 and 15, before effecting homocoupling to a biaryl were unsuccessful. Introduction of an acetyl group via initial bromination ortho to the hydroxyl group in naphthol 18, which bears an electron rich benzyl ether at C-7, was plagued by the formation of phenolic coupling product 42 and naphthoquinone 43. Bromination of naphthol 45, bearing a less electron rich triflate group at C-7, also afforded binaphthol 47 resulting from phenolic coupling as well as naphthoquinone 48 when using N-bromosuccinimide at low temperature.
