A Pd-catalyzed three-component cross-coupling reaction of vinyl iodide, N-tosylhydrazone, and carbon nucleophiles is reported, and a one-pot procedure is also developed. The cross-coupling is proposed to proceed through a palladium-carbene migratory insertion, carbopalladation other than classic palladium-carbene migratory insertion, and beta-H elimination. Moreover, the reaction proceeds under mild conditions and with high stereoselectivity.

The first example of near-room-temperature alpha-arylation of benzo[b]thiophenes is reported. The discovery rests on the observation of a switch in alpha-/beta-regioselectivity at different loadings of Pd2(dba)3·CHCl3 in the coupling between benzo[b]thiophene and 4-iodotoluene. We show that this unprecedented regioselectivity switch is driven by a Ag(I)-mediated C-H activation at the alpha-C-H position, which becomes the dominant mode of reactivity at low concentrations of Pd. Competition experiments, kinetic studies, KIE, and D/H scrambling experiments have been carried out supporting this mechanism.

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 52522-40-4 is helpful to your research. Reference of 52522-40-4

Treatment of AgNO3 with the Rh-Ru and Cu-Ru hetero bimetallic clusters, [PPN][RhRu5C(CO)14(cod)] and [PPh4]2[CuRu6C(CO)16Cl], afforded novel three-component complexes having one silver-, and two silver-bridges between respective cluster units, [PPN]{Ag[RhRu5C(CO)14(cod)]2} and [PPh4]2{Ag2[CuRu6C(CO)16Cl]2}, respectively. Reaction of the ruthenium-copper cluster [PPh4]2{Cu4[Ru6C(CO)16]2Cl2} (6) with Pd2(dba)3 · CHCl3 gave another three-component cluster [PPh4]2{Cu4Pd2[Ru6C(CO)16]2Cl2} by incorporation of two palladium atoms. However, a similar reaction of 6 with Pt(dba)2 gave only a two-component cluster complex, [PPh4]2{Pt2[Ru6C(CO)15]2}, while the reaction of silver analog [PPN]2{Ag4[Ru6C(CO)16]2Cl2} with Pd2(dba)3 · CHCl3 resulted in the formation of known ruthenium-palladium cluster [PPN]2{Pd4[Ru6C(CO)16]2}. Treatment of 6 with [RhCl(CO)2]2 gave two two-component clusters, [PPh4][RhRu5C(CO)16] and [PPh4]2{Cu7[Ru6C(CO)15]2Cl3}. All the new mixed-metal high nuclearity clusters have been characterized by single crystal X-ray analyses.

Palladium-catalyzed intramolecular cross-coupling reactions between aryl iodides and allyl moieties were successfully demonstrated in the presence of palladium catalyst, tri-o-tolylphosphine, a tertiary amine, and water. Several kinds of trans-2,4-disubstituted 1,2,3,4-tetrahydroquinolines were synthesized in 73-88% yields with excellent diastereoselectivities. This method was further applied to a large variety of substrates to form five-, six-, and seven-membered carbo- and heterocycles in good yields, regardless of the ring-containing atom, via microwave-assisted conditions.

A mono-6-O-propargyl permethylated beta-cyclodextrin, 3, has been prepared by two synthetic routes as a versatile building block for the construction of cyclodextrin dimers and trimers with a core junction which is potentially electron conducting. Glaser-Hay coupling of 3 gave beta-cyclodextrin dimer 6, and Pd(0)-catalysed coupling allowed the preparation of a cyclodextrin dimer with a 1,4-phenylene bridge, 7, and a cyclodextrin trimer based on a 1,3,5-trisubstituted benzene, 8. All compounds have been fully characterised, and in particular, detailed analysis by 2D NMR spectroscopic techniques has provided useful insight into the identities of the compounds. The detailed full characterisation of mono-3,6-anhydro-heptakis(2,3- O-methyl)-hexakis(6-O-methyl)-beta-cyclodextrin, 5, is also described. Product 5 is formed during the methylation of compound 3, and its formation was found to be sensitive to the reaction conditions. The absorption and fluorescence spectra of the phenylene-bridged dimer 7 and trimer 8 are also reported. They show different properties of the excited state based on the different electronic coupling imposed by the phenylene core. The Royal Society of Chemistry 2005.

A recently reported palladium-catalyzed allylic substitution of vinyl-substituted cyclic carbonates (VCCs) with aryl amines represents a rare example of a regio- and enantioselective synthesis of alpha,alpha-disubstituted allylic N-aryl amines. However, the underlying reasons for this unusual selectivity profile remain elusive. In the present work, density functional theory (DFT) calculations in combination with mechanistic control experiments were performed to elucidate in detail this allylic amination manifold and the origin of the regio- and enantioselectivity. The combined data show that after oxidative addition of the VCC to Pd0, the nucleophilic attack via an originally proposed outer-sphere pathway gives, however, the opposite regioisomer compared to the experimental results. Instead, nucleophilic attack of the amine reagent via a unique type of chelation-assisted, inner-sphere pathway accounts for the experimentally observed ?branched? regioselectivity and high enantio-control.
