Synthesis of Pyridiniumboranephosphonate Diesters and Related Compounds using Trityl Cation as a Borane Hydride Acceptor
Rachwalak, Marta,Go??biewska, Justyna,Jakubowski, Tomasz,Stawinski, Jacek
, p. 509 - 517 (2021)
Boranephosphonate diesters react with pyridine and some tertiary amines in the presence of dimethoxytrityl chloride used as a borane hydride acceptor, to afford the boron-modified phosphodiester analogues containing a P-B-N structural motif. The reaction provides a convenient entry to pyridinium- and ammoniumboranephosphonates derived from the corresponding alkyl, aryl, or nucleoside boranephosphonate diesters. Some aspects of the synthetic protocol, mechanistic features related to a possible intermediate involved, and the role of the solvents used, are discussed.
Electrochemical synthesis of phosphorus esters from white phosphorus in the presence of copper complexes and ethanol

, p. 929 - 938 (2003)
In the presence of white phosphorus the redox potentials of the copper ions change and the potential of the reduction wave of CuI/Cu 0 shifts noticeably toward more positive values. The Cu I-P4 complex is characterized by a lower value of the electrochemical gap, that is, higher polarizability and reactivity compared to those of the free CuI cation. Phosphorus esters can be synthesized from P4 and ethanol. The latter is in the composition of the copper(II) complexes, which act as a catalyst-charge mediator.

Paragraph 0022-0032, (2021/09/15)
The invention relates to a synthetic method of diethyl phosphite. The method comprises the following steps: adding triethyl phosphite into a stirring reactor and heating to 30 - 60 in 70 - 80 °C minutes; carrying out chromatographic analysis by adding water to the stirring reactor for 60 minutes; and controlling the triethyl phosphite ≤ 0.3% to open the receiving bottle to carry out pressure reduction and rectification. The method is prepared by direct reaction of triethyl phosphite and water, and a solvent is not needed in the traditional process. No catalyst is needed, the reaction is mild, the yield is high, and the yield can reach ≥ 99%. Raw materials are easy to obtain, and the production cost can be effectively reduced. The method has the advantages of simple operation, no side reaction in the reaction process, good product purity, less 99% or more product purity, low cost, safety and environmental protection, and is suitable for industrial production.

The outcome of reaction of sodium N-benzylideneglycinate containing water in its crystal lattice with dialkyl chlorophosphites depends on the mode of addition of the latter. Upon the simultaneous mixing of the reactants, 1,4-bis[α-(dialkoxyphosphoryl)benz
