Pd-Catalyzed enantioselective synthesis of 2-methyl-3-methyleneindoline

A Pd-catalyzed enantioselective synthesis of 2-methyl-3-methyleneindoline in up to 89% yield and 84% ee from racemic vinyl benzoxazinanones has been developed with the help of (R,R)-BenzP* ligand. Mechanism studies support the formation of palladacyclobutane as the key intermediate via C2 attack to pi-allyl Pd complex. The beta-hydride elimination provides a new reaction pathway for the palladacyclobutane.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 32005-36-0 is helpful to your research. Application of 32005-36-0

Synthesis, Characterization, and Application of Segphos Derivative Having Diferrocenylphosphino-Donor Moieties

An axially chiral bisphosphine, Fc-Segphos (1), which possesses diferrocenylphosphino-donor moieties, was prepared as a racemate, and its optical resolution was achieved by the use of chiral HPLC. Ligand 1 coordinated to a palladium(II) cation in a bidentate fashion to construct a unique chiral environment at the palladium center due to the sterically demanding ferrocenyl groups. Ligand (R)-1 was applied in the palladium-catalyzed asymmetric synthesis of axially chiral allenes showing good enantioselectivity of up to 92% ee. In general, (R)-1 displayed better enantioselectivity than the parent Segphos in the palladium-catalyzed reaction, and the Pd/(R)-1 species showed up to 18% ee enhancement over the (R)-Segphos-derived palladium catalyst.

Palladium-catalyzed reduction of carboxylic acids to aldehydes with hydrosilanes in the presence of pivalic anhydride

A palladium catalyst system that allows the reduction of carboxylic acids to the corresponding aldehydes with hydrosilanes as reducing agent and pivalic anhydride as an indispensable reagent has been developed. A simple mixture of commercially available bis(dibenzylideneacetone)palladium(0) [Pd(dba) 2], tri(para-tolyl)phosphane and methylphenylsilane realized the reduction of various aliphatic carboxylic acids as well as benzoic acids to aldehydes in good to high yields.

In situ generation of highly active bis(N-heterocyclic)carbene palladium as an efficient catalyst in direct S-arylation of methylphenyl sulfoxide and the Heck reaction: Ligand steric effects in product selectivity

The use of 1,3-bis(N-heterocyclic)carbene ligands with different alkyl wingtip groups (alkyl = methyl, isopropyl and tert-butyl) is an effective method for the palladium-catalysed direct S-arylation of methylphenyl sulfoxide and C?C coupling of various of aryl halides with alkenes. The reactions proceed in moderate to good yields. Interestingly, it is shown experimentally that, by using bulkier bidentate N-heterocyclic carbene ligands, more selective catalytic systems towards cis products in Heck coupling reactions can be achieved.

The methoxypalladation product <>2> from the title complex (3) undergoes relatively slow decomposition in solution via at least two pathways.The major pathway leads to complexes containing the acetal MeSCH2CMe2CH2CH(OMe)2 or the corresponding aldehyde.An important intermediate in this pathway is the alpha-methoxyalkylpalladium(II) derivative<>2> which has also been generated by reaction of MeSCH2CMe2CH2CH(Cl)OMe with bis(dibenzylideneacetone)palladium(0).The minor pathway involves hydride transfer between ligand molecules and leads to complexes containing both oxidised and reduced ligands.More efficient hydride transfer is observed when the product <>2> from reaction of (3) with HgPh2 is treated with MeSCH2CMe2CH=CH2.

Rational design of cyclopropane-based chiral PHOX ligands for intermolecular asymmetric Heck reaction

A novel class of chiral phosphanyl-oxazoline (PHOX) ligands with a conformationally rigid cyclopropyl backbone was synthesized and tested in the intermolecular asymmetric Heck reaction. Mechanistic modelling and crystallographic studies were used to predict the optimal ligand structure and helped to design a very efficient and highly selective catalytic system. Employment of the optimized ligands in the asymmetric arylation of cyclic olefins allowed for achieving high enantioselectivities and significantly suppressing product isomerization. Factors affecting the selectivity and the rate of the isomerization were identified. It was shown that the nature of this isomerization is different from that demonstrated previously using chiral diphosphine ligands.
