Effect of the Bite Angle of Diphosphine Ligands on Activity and Selectivity in the Nickel-catalysed Hydrocyanation of Styrene

The application of diphosphines with large bite angles (betan = 101-109 deg) in nickel catalysts leads to successful, regioselective hydrocyanation of styrene.

The coordination behaviour of large natural bite angle diphosphine ligands towards methyl and 4-cyanophenylpalladium(II) complexes

The structures of neutral and ionic 4-cyanophenylpalladium(II) and methylpalladium(II) complexes containing bidentate phosphine ligands were investigated in solution and in the solid state. Diphosphine ligands with a xanthene and a ferrocene backbone were used. New bis(dialkylphosphino) substituted Xantphos ligands were synthesised. 1H NMR and 31P NMR spectroscopy, conductivity measurements, UV-Vis spectroscopy, and X-ray crystallography were used to elucidate the structures of the complexes. Subtle changes of the phosphine ligands govern the coordination mode of the ligand. A variety of bidentate cis-, and trans-coordination and terdentate P-O-P, P-S-P and P-Fe-P coordination modes of the ligands were observed.

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: 161265-03-8, you can also check out more blogs about161265-03-8

New, Highly Efficient Work-Up Protocol for Sulfonated Diphosphines

Isolation of a series of sulfonated diphosphines via a new highly efficient method is described. The work-up procedure involves the precipitation of the sulfonated ligand prior to neutralization, and subsequent removal of the sulfuric acid by filtration and washing. Great advantages of this procedure are its simplicity and easiness to scale-up while co-production of large amounts of sulfate salts is avoided.

Controllable Isomerization of Alkenes by Dual Visible-Light-Cobalt Catalysis

We report herein that thermodynamic and kinetic isomerization of alkenes can be accomplished by the combination of visible light with Co catalysis. Utilizing Xantphos as the ligand, the most stable isomers are obtained, while isomerizing terminal alkenes over one position can be selectively controlled by using DPEphos as the ligand. The presence of the donor?acceptor dye 4CzIPN accelerates the reaction further. Transformation of exocyclic alkenes into the corresponding endocyclic products could be efficiently realized by using 4CzIPN and Co(acac)2 in the absence of any additional ligands. Spectroscopic and spectroelectrochemical investigations indicate CoI being involved in the generation of a Co hydride, which subsequently adds to alkenes initiating the isomerization.

Palladium-catalyzed difunctionalization of enol ethers to amino acetals with aminals and alcohols

A new strategy was developed for intercepting the palladium-alkyl species generated in Heck reaction via nucleophilic addition prior to the step of migratory insertion, which leads to a new palladium-catalyzed difunctionalization of enol ethers with aminals and alcohols to afford amino acetals. Mechanistic studies suggested that the cationic cyclometalated Pd(II) complex generated by the oxidative addition of aminal to a Pd(0) species was crucial for this unusual transformation.

Synthesis, structures and photophysical properties of copper(I) 2-(2-benzimidazolyl)-6-methylpyridine complexes with different diphosphine ligands

A series of new Cu(I) 2-(2-benzimidazolyl)-6-methylpyridine (Hbmp) complexes containing five different diphosphine auxiliary ligands have been synthesized and well characterized. It is revealed that all Cu(I) atoms display distorted N2P2tetrahedral geometries with distinct P?Cu?P bond angles regulated by diverse diphosphine ancillary ligands, in which Hbmp serves as a charge-neutral chelating ligand without the deprotonation of the benzimidazolyl-NH while the diphosphine ligand adopts a bridging or chelating coordination mode. It is demonstrated that all these Cu(I) complexes show a relatively weak low-energy absorption in solution and exhibit good luminescence properties in solution and solid states at room temperature, which are more markedly influenced by the P?Cu?P bond angle.
