CuSO4/Al2O3 as a new effective and recyclable catalyst for the arylation of dialkyl phosphites
Karlstedt,Anokhin,Beletskaya
, p. 2498 - 2499 (2013)
A new effective recycled catalyst CuSO4/Al2O 3, which performs the phosphorylation of aryl halides and bromostyrene, was proposed.
An intramolecular Arbuzov rearrangement initiated by anodic oxidation

, p. 1625 - 1628 (1996)
Dialkyl phenylphosphonite PhP(OR)2 (R = Et, Me) undergoes an intramolecular Arbuzov rearrangement upon electrolysis at an anode in acetonitrile under an oxygen atmosphere to yield alkyl alkylphenylphosphinate PhRP(=O)(OR). The results here suggest that the rearrangement takes place through a radical-chain mechanism initiated by anodic oxidation of the phosphonite to the corresponding cation radical.
Evaluation of transition metal catalysts in electrochemically induced aromatic phosphonation
Strekalova, Sofia,Khrizanforov, Mikhail,Budnikova, Yulia
, (2019)
Voltammetry provides important information on the redox properties of catalysts (transition metal complexes of Ni, Co, Mn, etc.) and their activity in electrocatalytic reactions of aromatic C-H phosphonation in the presence of a phosphorus precursor, for

The ability to selectively react one functional group in the presence of another underpins efficient reaction sequences. Despite many designer catalytic systems being reported for hydroboration reactions, which allow introduction of a functional handle fo
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.
Selective hydrolysis of phosphorus(v) compounds to form organophosphorus monoacids
Ash, Jeffrey,Cordero, Paula,Huang, Hai,Kang, Jun Yong
, p. 6007 - 6014 (2021/07/21)
An azide and transition metal-free method for the synthesis of elusive phosphonic, phosphinic, and phosphoric monoacids has been developed. Inert pentavalent P(v)-compounds (phosphonate, phosphinate, and phosphate) are activated by triflate anhydride (Tf2O)/pyridine system to form a highly reactive phosphoryl pyridinium intermediate that undergoes nucleophilic substitution with H2O to selectively deprotect one alkoxy group and form organophosphorus monoacids.
