The Dimeric Pyramidal Cu2O6(H2O)2Unit – A Structural Invariant of a Homologous Series of Copper-Layered Phosphonates

Two new layered copper hybrid materials, namely, the copper thiophene-2,5-diphosphonate [Cu2(H2O)2(O3P–C4H2S–PO3)] (Pnma; a = 7.525 ?, b = 18.292 ?, c = 7.520 ?) and the copper 3-fluorophenylphosphonate Cu(H2O)PO3–C6H4F (P21/c; a = 14.305 ?, b = 7.550 ?, c = 7.479 ?, β = 92.32°), have been synthesized. These compounds belong to the large homologous Cu(H2O)PO3R/[Cu2(H2O)2(O3P–R–PO3)] series, the structure of which is dictated by the presence of isolated dimeric pyramidal Cu2O6(H2O)2units. The role of the Cu/H2O molar ratio of 1 in the stabilization of such a structure is discussed in connection with the Jahn–Teller effect of the copper cation. The study of the magnetic behavior of polycrystalline samples of the two compounds has revealed antiferromagnetic coupling between the copper ions. The interactions within the dimeric unit were estimated by the Bleaney–Bowers law with the spin Hamiltonian H = –JSCu1SCu2+ gβHS: J = –6.27 cm–1for [Cu(H2O)PO3]2C4H2S, and J = –6.07 cm–1for Cu(H2O)PO3–C6H4F.

Microwave assisted P–C coupling reactions without directly added P-ligands

Our group introduced a green protocol for the Pd(OAc)2- or NiCl2-catalyzed P–C coupling reaction of aryl halides and various > P(O)H-compounds under MW conditions without directly added P-ligands. The reactivity of a few aryl derivatives in the Pd(OAc)2-catalyzed Hirao reaction was also studied. An induction period was observed in the reaction of bromobenzene and diphenylphosphine oxide. Finally, the less known copper(I)-promoted P–C coupling reactions were investigated experimentally. The mechanism was explored by quantum chemical calculations.

Decarbonylative Phosphorylation of Amides by Palladium and Nickel Catalysis: The Hirao Cross-Coupling of Amide Derivatives

Considering the ubiquity of organophosphorus compounds in organic synthesis, pharmaceutical discovery agrochemical crop protection and materials chemistry, new methods for their construction hold particular significance. A conventional method for the synthesis of C?P bonds involves cross-coupling of aryl halides and dialkyl phosphites (the Hirao reaction). We report a catalytic deamidative phosphorylation of a wide range of amides using a palladium or nickel catalyst giving aryl phosphonates in good to excellent yields. The present method tolerates a wide range of functional groups. The reaction constitutes the first example of a transition-metal-catalyzed generation of C?P bonds from amides. This redox-neutral protocol can be combined with site-selective conventional cross-coupling for the regioselective synthesis of potential pharmacophores. Mechanistic studies suggest an oxidative addition/transmetallation pathway. In light of the importance of amides and phosphonates as synthetic intermediates, we envision that this Pd and Ni-catalyzed C?P bond forming method will find broad application.

A "green" variation of the Hirao reaction: The P-C coupling of diethyl phosphite, alkyl phenyl-H-phosphinates and secondary phosphine oxides with bromoarenes using a P-ligand-free Pd(OAc)2 catalyst under microwave and solvent-free conditions

The P-C coupling of diethyl phosphite, alkyl phenyl-H-phosphinates, diphenylphosphine oxide and dialkylphosphine oxides with bromoarenes may be performed in the presence of a P-ligand-free Pd(OAc)2 catalyst and triethylamine under microwave-assisted (MW) and, in almost all cases, solvent-free conditions to afford diethyl arylphosphonates, alkyl diphenylphosphinates, aryldiphenylphosphine oxides and dialkylphenylphosphine oxides, respectively. This is the "greenest" accomplishment of the well-known Hirao reaction that has now been found to have general application for a broad spectrum of >P(O)H species with different reactivity and a great variety of substituted bromobenzenes. The alkyl phenyl-H-phosphinates were prepared by the MW-promoted alkylation of phenyl-H-phosphinic acid in the absence of any solvent. This journal is the Partner Organisations 2014.

A series of substituted diethyl arylphosphonates was synthesized by the microwave-assisted Arbuzov reaction of triethyl phosphite and aryl bromides in the presence of NiCl2 as the catalyst under solvent-free conditions in good yields. The resulting phosphonates were hydrolyzed to the corresponding arylphosphonic acids whose acidity was evaluated by physicochemical methods.
