Metal- and oxidant-free S-P(O) bond construction: Via direct coupling of P(O)H with sulfinic acids

We have developed a simple and convenient method for S-P(O) bond formation between R2P(O)H and sulfinic acids under metal-, oxidant-, and halogen-free conditions. The current method is compatible with a broad range of substituents on various substrates including halogens and heterocyclic moieties. The synthetic potential of this method was further highlighted by the expeditious synthesis of optically active P-chiral phosphorothioates via stereospecific coupling.

New stable phosphorus ylide (p-tolyl)3P = CHCOC6H4 (p-CN) and its metal complexes: Crystal and molecular structure, theoretical study and antibacterial investigation

A new stable phosphorus ylide (p-tolyl)3P = CHCOC6H4(p-CN) (Y) was synthesized and a series of novel complexes based on metalated phosphorus ylides were prepared through the reaction of (p-tolyl)3P = CHCOC6H4(p-CN) with mercury(II) halides, AgNO3 and Cd(NO3)2 in equimolar ratios using MeOH or CH2Cl2 as solvent. Characterization of the obtained compounds was also performed by elemental analysis, FT-IR, 1H, 31P, and 13C NMR techniques. The crystal structure of complex [Y?HgCl2] was determined by X-ray diffraction method, in which the coordination of the prepared ylide occurred to the Hg center in a symmetric halide-bridged structure. The structure and nature of Hg-C bond in the aforementioned complex were studied based on DFT method using Natural bond orbital (NBO), Energy-decomposition analysis (EDA) and ETS-NOCV. The antibacterial applicability of the synthesized mercury(II) complexes was explored against five Gram-positive and four Gram-negative bacteria types. The novelty of the presented work is: (1) the synthesis of five new complexes, (2) conducting theoretical and (3) biological investigation of the prepared complexes.

Electrochemical Oxidative Dehydrogenative Phosphorylation of N-Heterocycles with P(O)-H Compounds in Imidazolium-Based Ionic Liquid

We report a direct and green electrochemical oxidative cross-dehydrogenative coupling reaction of N-heterocycles with hydrogen phosphoryl compounds under external oxidant-free conditions. Various phosphorylation products of substituted carbazoles and indoles are assembled in modest to excellent yields. A hydrogen release process is preliminarily demonstrated and H2 is the sole byproduct. An imidazolium based ionic liquid is selected as the optimal electrolyte.

Unexpected bell-shaped effect of the ligand on the rate of the oxidative addition to palladium(0) complexes generated in situ from mixtures of Pd(dba)2 and para-substituted triarylphosphines

As with PPh3, mixtures of Pd(dba)2 and n L (L = para-Z-substituted triphenylphosphines, n ? 2) in DMF lead to the formation of Pd(dba)L2 and PdL3 in equilibrium with PdL2. The equilibrium between Pd(dba)L2 and PdL3 is more in favor of PdL3 when the phosphine is less electron rich. In other words, the exchange of the dba ligand by a phosphine from Pd(dba)L2 to form PdL3 is more favored when the phosphine is less electron rich. The less ligated complex PdL2 is the reactive species in the oxidative addition with phenyl iodide. It was therefore expected that the rate of the oxidative addition would increase when the phosphine is more electron rich. However, surprisingly, when the palladium(0) complex is generated from mixtures of Pd(dba)2 and n L (n ? 2), the oxidative addition does not follow a linear Hammett correlation and the reactivity of the palladium(0) complex exhibits a maximum value. This is due to two antagonist effects. Indeed, the overall reactivity in the oxidative addition is governed by two factors: the intrinsic reactivity of PdL2 and its concentration. When the phosphine becomes more electron rich, the complex PdL2 becomes more nucleophilic and its intrinsic reactivity in the oxidative addition increases. However, when the phosphine becomes more electron rich, the concentration of PdL2 decreases because the equilibrium between the palladium(0) complexes becomes more in favor of Pd(dba)L2. These results emphasize the crucial role of the dba ligand on the reactivity of palladium(0) complexes generated in situ in mixtures of Pd(dba)2 and phosphines.

Metal-Free, Visible Light-Photocatalyzed Synthesis of Benzo[b]phosphole Oxides: Synthetic and Mechanistic Investigations

Highly functionalized benzo[b]phosphole oxides were synthesized from reactions of arylphosphine oxides with alkynes under photocatalytic conditions by using eosin Y as the catalyst and N-ethoxy-2-methylpyridinium tetrafluoroborate as the oxidant. The reaction works under mild conditions and has a broad substrate scope. Mechanistic investigations have been undertaken and revealed the formation of a ground state electron donor-Acceptor complex (EDA) between eosin (the photocatalyst) and the pyridinium salt (the oxidation agent). This complex, which has been fully characterized both in the solid state and in solution, turned out to exhibit a dual role, i.e., the oxidation of the photocatalyst and the formation of the initiating radicals, which undergoes an intramolecular reaction avoiding the classical diffusion between the two reactants. The involvement of ethoxy and phosphinoyl radicals in the photoreaction has unequivocally been evidenced by EPR spectroscopy.

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.Safety of Di(naphthalen-2-yl)phosphine oxide, you can also check out more blogs about78871-05-3
