Palladium-catalyzed enantioselective allylic alkylations through C-H activation

A new ligand class: The title reaction was made possible by the discovery of a new class of phosphoramidite ligands. A variety of sterically and electronically diverse allylarenes undergo reaction with 2-acetyl-1-tetralones to form quaternary carbon stereocenters. This is a conceptually and mechanistically distinct strategy from traditional methods for the synthesis of enantioenriched allylic substitution products. 2,6-DMBQ=2,6- dimethylbenzoquinone.

Anion-exchange-triggered 1,3-Shift of an NH proton to iridium in protic N-heterocyclic carbenes: Hydrogen-bonding and Ion-pairing effects

Proton release: A series of five-coordinate iridium(l) phosphine complexes with protic N-heterocyclic carbene ligands have been prepared which display NH-Cl hydrogen bonding (see scheme; cod = 1,5-cyclooctadiene). Exchange of the chloride for less coordinating anions triggers the reversible 1,3-shift of the NH proton to the iridium, which is thought to proceed by a novel water-assisted protonrelay mechanism.

Intramolecular C-H activation by air-stable Pt(II) phosphite complexes

Air-stable L2PtMe2 complexes ligated by bulky aryl phosphite ligands were synthesized and characterized. The aryl phosphite ligands were prepared from substituted phenols and PCl3 or P(NMe2)3 without the use of an external base. The steric environment of the phenol controlled the number of substitutions at P(NMe2)3, resulting in selective formation of P(NMe2)(O-2,6-Me2C6H3)2. The phosphite ligands and their corresponding platinum(II) complexes were found to be air stable and robust. X-ray diffraction structures of the platinum(II) complexes were obtained in order to determine the steric environment around the metal centers. Thermolysis of the L2PtMe2 complexes in C6D6 at 100 C results in loss of methane and formation of one major platinum-containing product in high yield. The products of thermolysis were found to be a result of cyclometalation by C-H activation of a sp3 C-H bond in the ligand to form a 6-membered ring, as confirmed by X-ray crystallography.

Control of Chemo-, Regio-, and Enantioselectivity in Copper Hydride Reductions of Morita-Baylis-Hillman Adducts

Nonracemically ligated copper hydride can be used to effect tandem SN2?/1,2-reductions of racemic Morita-Baylis-Hillman (MBH) acetates to access enantioenriched chiral allylic alcohols with defined olefin geometry. MBH esters, including those with beta-substitution, can be transformed to stereodefined enoates by taking advantage of a bulky, oligomeric, in situ generated trialkoxysiloxane leaving group. Finally, an atypical conversion of easily arrived at MBH alcohol derivatives to nonracemic allylic alcohols is disclosed.

Design and preparation of new palladium precatalysts for C-C and C-N cross-coupling reactions

A series of easily prepared, phosphine-ligated palladium precatalysts based on the 2-aminobiphenyl scaffold have been prepared. The role of the precatalyst-associated labile halide (or pseudohalide) in the formation and stability of the palladacycle has been examined. It was found that replacing the chloride in the previous version of the precatalyst with a mesylate leads to a new class of precatalysts with improved solution stability and that are readily prepared from a wider range of phosphine ligands. The differences between the previous version of precatalyst and that reported here are explored. In addition, the reactivity of the latter is examined in a range of C-C and C-N bond forming reactions.

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 213697-53-1 is helpful to your research., Electric Literature of 213697-53-1

Palladium(II) and platinum(II) complexes with tridentate iminophosphine ligands; synthesis and structural studies

The previously synthesised Schiff-base ligands 2-(2-Ph2PC 6H4N=CH)-R?-C6H3OH (R? = 3-OCH3, HL1; 5-OCH3, HL2; 5-Br, HL3; 5-Cl, HL4) were prepared by a faster, more efficient route involving a microwave assisted co-condensation of 2-(diphenylphosphino) aniline with the appropriate substituted salicylaldehyde. HL1-4 react directly with MIICl2 (M = Pd, Pt) or Pt III2(cod) affording neutral square-planar complexes of general formula [MIICl(eta3-L1-4)] (M = Pd, Pt, 1-8) and [PtIII(eta3-L1-4)] (M = Pd, Pt, 9-12). Reaction of complexes 1-4 with the triarylphosphines PR3 (R = Ph, p-tolyl) gave the novel ionic complexes [PdII(PR 3)(eta3-L1-4)]ClO4 (13-20). Substituted platinum complexes of the type [PtII(PR 3)(eta3-L1-4)]ClO4 (R = P(CH 2CH2CN)3 21-24) and [PtII(P(p-tolyl) 3)(eta3-L3.4)]ClO4 (25 and 26) were synthesised from the appropriate [PtIICl(eta3- L1-4)] complex (5-8) and PR3. The complexes are characterised by microanalytical and spectroscopic techniques. The crystal structures of 3, 6, 10, 15, 20 and 26 were determined and revealed the metal to be in a square-planar four-coordinate environment containing a planar tridentate ligand with an O,N,P donor set together with one further atom which is trans to the central nitrogen atom.

STERIC AND ELECTRONIC EFFECTS IN LIGAND SUBSTITUTION OF METAL CARBONYLS. RAPID KINETICS OF LABILE CARBONYLMANGANESE COMPLEXES BY TRANSIENT ELECTROCHEMICAL TECHNIQUES.

The ligand substitution kinetics of a series of carbonylmanganese cations MeCpMn(CO)//2L** plus with L equals 3- and 4-substituted pyridine ligands are measured for a variety of phosphine nucleophiles N of differing steric and electronic properties. The unified free energy relationship is shown for the first time to accommodate all the extensive rate data, if the steric effect is evaluated by Tolman’s cone angles for the phosphines, and the electronic effects are evluated by the acid-base dissociation constants of the pyridine ligands and the phosphine nucleophiles. The range of second-order rate constants k//1 for ligand substitution of MeCpMn(CO)//2L** plus extends over four decades from 3. 0 to 2 multiplied by 10**4 M** minus **1 s** minus **1. The mechanism of ligand substitution of metal carbonyls is central to the successful catalysis of a variety of important processes leading to the reduction of carbon monoxide.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Product Details of 4020-99-9, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 4020-99-9, in my other articles.
