Diphenyliodonium Ion/Et3N Promoted Csp2-H Radical Phosphorylation of Enamides

This work reports a simple and efficient method for the direct phosphorylation of enamide under metal-free conditions. The P-centered radicals, derived from secondary phosphine oxides, are generated under mild reaction conditions in the presence of diphenyliodonium salt and Et3N and are introduced onto a range of enamides in good isolated yields. The method features broad substrate scope, good functional group tolerance, and efficient scale-up.

Organocatalytic, regioselective allylic- and 1,6-substitution of quinone monoketals with diaryl H-phosphine oxides

An efficient selective synthesis of C- and O-phosphoryl-substituted phenols from easily available diaryl H-phosphine oxides with quinone monoketals (QMAs) has been developed. With the assistance of opponent characteristic additives (e.g., H2O and Et3N), diaryl H-phosphine oxides could selectively proceed the allylic- and 1,6-substitution to conjugate with the C-/O- positions of QMAs. The reported protocol is green and practical, and represents an efficient method to functionalize C-/O-phosphoryl-substituted phenols with moderate to good yields.

Copper-catalyzed C?P cross-coupling of secondary phosphines with (hetero)aromatic bromide

A novel and convenient approach to the synthesis of various tertiary phosphines via a copper-catalyzed cross-coupling of (hetero)aromatic bromide with secondary phosphines has been developed. The reaction employs cheap copper as the catalyst, 2,6-bis(N-methylaminomethyl)pyridine (L4) as a perfect ligand and KOtBu as a base; all reactions are carried out under argon atmosphere. A variety of sterically hindered and/or functionalized substrates were found to react under these reaction conditions to provide products in good to excellent yields. Moreover, ten new tertiary phosphines were first reported in this process.

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.

Ni-Catalyzed C-P Coupling of Aryl, Benzyl, or Allyl Ammonium Salts with P(O)H Compounds

A methodology that allows for the construction of C-P bonds via the nickel-catalyzed cross-coupling of organoammonium salts with appropriate phosphorus nucleophiles has been developed. Aryl-, pyridyl-, benzyl-, and allyl-ammonium triflates can be employed as the electrophiles. The employed phosphorus-based nucleophiles included diaryl/dibutyl phosphine oxide, dialkyl phosphonates, and ethyl phenylphosphinate. Functional groups OMe, CN, CF3, F, Cl, C(O)NMe2, and C(O)tBu were tolerated.

General Oxidative Aryl C-P Bond Formation through Palladium-Catalyzed Decarbonylative Coupling of Aroylhydrazides with P(O)H Compounds

Oxidative C-C/P-H cross-coupling is achieved via Pd-catalyzed decarbonylative cross-coupling of aroylhydrazides with P(O)H compounds. The unique cooperative reaction system, especially the Br¡ãnsted acid and bidentate phosphine ligand, allows the selective activation of the inert C-C bond and the suppression of the undesired oxidation and coordination of >P(O)-H compounds, leading to a general oxidative synthesis of aryl phosphorus compounds from easily available substrates.

Distal-selective hydroformylation using scaffolding catalysis

In hydroformylation, phosphorus-based directing groups have been consistently successful at placing the aldehyde on the carbon proximal to the directing group. The design and synthesis of a novel catalytic directing group are reported that promotes aldehyde formation on the carbon distal relative to the directing functionality. This scaffolding ligand, which operates through a reversible covalent bond to the substrate, has been applied to the diastereoselective hydroformylation of homoallylic alcohols to afford delta-lactones selectively. Altering the distance between the alcohol and the olefin revealed that homoallylic alcohols gives the distal lactone with the highest levels of regioselectivity.

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 Bis(4-(trifluoromethyl)phenyl)phosphine oxide, you can also check out more blogs about15929-43-8
