A highly efficient palladium-catalyzed intramolecular aminoalkylation of unactivated alkenes in the absence of an external ligand and oxidant is described. New C-N and C(sp3)-C(sp3) bonds are formed simultaneously. This general transformation allows for construction of diverse N-heterocycles. Mechanistic studies show that the process may involve a four-membered Pd(alkyl)amido intermediate.

The Pd-catalyzed 3-arylation of 2-oxindoles with aryl bromides, chlorides and triflates is found to proceed using i -Pr-BI-DIME and Me 2 -BI-DIME ligands. The mono-arylation of 3-unsubstituted oxindoles is accomplished using a Pd 2 (dba) 3 / i -Pr-BI-DIME catalyst system, and gives good yields of 3-aryloxindoles from aryl bromides and chlorides. The arylation of 3-substituted oxindoles is also possible using this catalyst/ligand system. The asymmetric arylation of 3-substituted oxindoles is accomplished using Me 2 -BI-DIME to furnish oxindoles bearing a quaternary C-3 stereocenter in enantiomeric ratios of up to 93:7.

An efficient and practical protocol for the synthesis of (E)-allylethers from readily available olefins with alcohols or phenols was developed. This aerobic oxidative allylic C-H oxygenation protocol features mild conditions, broad substrate scope, and high atom and step economy, making it a valuable and convenient synthetic method. Notably, molecular oxygen is the sole oxidant in this novel transformation.

The palladium(0)-catalyzed, ligand-controlled, regioselective addition of diaryl acetonitrile pronucleophiles to propargylic carbonates is reported. Selective formation of either terminal 1,3-dienyl or propargylated products is proposed to arise from a change in reaction mechanism controlled by the denticity of the coordinating ligand.

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: 52409-22-0, you can also check out more blogs about52409-22-0

Water-soluble diol-functionalized imidazolium ionic liquid 1, prepared from 2,2-bis(1-methyl-methyl-imidazolium)propane-1,3-diol bromide, potassium hydroxide, and malononitrile, was used as an efficient phosphine-free ligand for palladium-catalyzed arylation of aryl halides with acrylates in aqueous phase under mild conditions. It was found that the synergistic coordinating action of diol-functionalized imidazolium cation with CN-containing anion played the key role in improving the activity and stability of the catalyst.

The mechanism of the palladium-catalyzed synthesis of allylic silanes and boronates from allylic alcohols was investigated. 1H, 29Si, 19F, and 11B NMR spectroscopy was used to reveal key intermediates and byproducts of the silylation reaction. The tetrafluoroborate counterion of the palladium catalyst is proposed to play an important role in both catalyst activation as well as the transmetalation step. We propose that BF3 is generated in both processes and is responsible for the activation of the substrate hydroxyl group. An (eta3- allyl)palladium complex has been identified as the catalyst resting state, and the formation of (eta3-allyl)palladium complexes directly from allylic alcohols has been studied. Kinetic analysis provides evidence that the turnover limiting step is the transmetalation, and insights into notable similarities between the borylation and the silylation reaction mechanisms enabled us to considerably improve the stereoselectivity of the borylation.
