Convenient Formation of Triarylphosphines by Nickel-Catalyzed C-P Cross-Coupling with Aryl Chlorides

A convenient strategy has been developed for the preparation of various phosphine ligands in good to excellent yields through a nickel-catalyzed C-P bond-forming step.

A Comparison of the Effects of Steric Crowding at Phosphorus on the Steric Course of Wittig Reactions of Stabilised and Semistabilised Ylides

The cis-trans ratio of the alkenes formed in Wittig reactions of semistabilised ylides (derived from benzyltriarylphosphonium salts in ethanolic sodium ethoxide) with benzaldehyde, acetaldehyde or trimethylacetaldehyde increases as steric crowding at phosphorus increases.In contrast, the cis-trans ratio of the unsaturated esters formed in the related reactions of the stabilised ethoxycarbonylmethylene ylides decreases as steric crowding at phosphorus increases.The relevance of these results to recent proposals for the mechanism of the Wittig reaction is considered. – Keywords: Alkene cis-trans Ratio, Reaction Mechanism

Cyclometallation of polydentate ligands containing pyrazole groups, including the synthesis of platinum(IV) complexes with tripodal – ligand systems

Dimethylplatinum(II) complexes, PtR2(L), have been made by reaction of 2 with a range of polydentate nitrogen donor ligands containing one or more pyrazol-1-yl (pz) donor groups, including the new ligand bis(pyrazol-1-yl)(thien-2-yl)methane.The complexes give cis-PtMe2(py)2 when dissolved in pyridine at ambient temperature, except for PtMe2(L) (L = (pz)2CH2, (pz)2C(H)Ph, (pz)3CH, or (pz)2(mim)CH (mim = N-methylimidazol-2-yl)), which undergo cyclometallation at a C(5) position of one pyrazol-1-yl ring.The cyclometallated ligands have been examined as ‘isoelectronic’ analogues of nitrogen donor poly(pyrazol-1-yl)alkane and poly(pyrazol-1-yl)borate ligands.A carbon monoxide derivative, PtMe<(pz)2(C3H2N2)CH-N,C>(CO) (1d) and a series of phosphine complexes have been prepared.The complex PtMe<(pz)2(C3H2N2)CH-N,C>(py) (1a) and polymeric >n (2) undergo oxidative addition reactions with organohalides to give the platinum(IV) complexes (py)>X (7a-d) and fac-PtXMe(R)<(pz)2(C3H2N2)CH-N,N',C> (8a-b), respectively.The new reagent 1-bromo-2-(pyrazol-1-yl)ethane forms (pzCH2CH2-N,C)>Br (10), containing both – and – ligands.Reaction of MeI or PhCH2Br with PtMe2<(pz)3CH>> gives fac-PtXMe(R)<(pz)2(C3H2N2)CH-N,N',C> (8a,b) directly, and PtMe2<(pz)4C> undergoes a similar cyclometallation/oxidative addition in iodomethane to form fac-PtIMe2<(pz)3(C3H2N2)CH-N,N',C> (13).

High- and low-spin chelate complexes of iron featuring kappa-C,X-CH2C6H4X (X?= NMe2, PMe2, PPh2) and kappa-C,P-CH2PMe2 ligands

Several C,X-chelate complexes of iron were generated via standard metathetical procedures. Treatment of FeCl2 and LnFeCl2 (L = Me2IPr, n = 1; PMe3, n = 2) with anionic equivalents o-LiCH2C6H4NMe2, o-LiCH2C6H4PPh2, and LiCH2PMe2 led to the preparation of [Fe(o-CH2C6H4NMe2)]2(kappa-mu-CH2,N-o-CH2C6H4NMe2)2 (1, X-ray), [fac-Fe(kappa-C,P-o-CH2C6H4PPh2)3][Li(TMEDA)2] (2, X-ray), (Me2IPr)Fe(CH2C6H4-o-NMe2)2 (3-C,N), [(Me2IPr)2Fe](mu-kappa-C,P-CH2PMe2)2[Fe(kappa-C,P-CH2PMe2)2] (4, X-ray), and (PMe3)2Fe(kappa-C,P-CH2PMe2)2 (5). CH-Bond activation of cis-(Me3P)4FeMe2 with o-CH3C6H4PMe2 led to the generation of trans,cis-(PMe3)2Fe(kappa-C,P-CH2C6H4-o-PMe2)2 (6). Exposure of these compounds to [Cp2Fe][PF6], a 1e? oxidant, or AdN3, here construed as a 2e? oxidant, led to degradation in all cases, usually with the generation of carbon-carbon coupled ligands as byproducts. The inability of these systems to permit access to higher iron oxidation states is discussed.

Customized Buchwald-Type Phosphines Bearing an “Inverted” Pyrimidinium Betaine as an Aryl Group Surrogate – Synthesis and Coordination Chemistry with Gold(I)

A new ligand scaffold inspired by Buchwald-type phosphines is disclosed. Its design consists of the formal replacement of the distal aryl group of the original archetype by a pyrimidinium betaine connected to the o-phosphinophenyl moiety through the C-5 position of its malonate subunit. A productive synthetic pathway towards this phosphine is described along with its ability to coordinate to a gold(I) center. A weak bonding interaction between the metal center and the malonate group is observed in the solid state.

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 5931-53-3 is helpful to your research., Reference of 5931-53-3

delta-Hydrogen Abstraction from Alkyl and Phosphine Ligands Co-ordinated to Platinum(II); Formation of Benzoplatinacyclopentene Complexes

Reactions of (cod = cyclo-octa-1,5-diene) with Mg(CH2C6H4Me-o)Br and tertiary phosphines (PR3) afford cis- (R = Et or Ph), which on refluxing in xylene give the benzoplatinacyclopentene complexes via delta-hydrogen abstraction reactions.Using PPh2(C6H4Me-o), metallation of the phosphine is preferred and the first obtained product after refluxing in xylene is >.On further refluxing in xylene, this compound again eliminates o-xylene to give the known .Using P(C6H4Me-o)3, the bulkiness of the phosphine makes alkylation unfavourable and the fluxional Br> is obtained.The variable-temperature n.m.r. spectra of this compound are interpreted in terms of hindered rotation around the Pt-P and P-C bonds giving rise to two different conformers at low temperature, each with all methyl groups non-equivalent.The compounds have been identified by their spectroscopic properties and some of their reaction chemistry is discussed.
