We report a diaryldiselenide catalyst for cross-dehydrogenative nucleophilic functionalization of hydrophosphoryl compounds. The proposed organocatalytic cycle closely resembles the mechanism of the Atherton-Todd reaction, with the catalyst serving as a recyclable analogue of the halogenating agent employed in the named reaction. Phosphorus and selenium NMR studies reveal the existence of a P-Se bond intermediate, and structural analyses indicate a stereospecific reaction.

A metal-, toxic chloride reagent-free activating strategy of various phosphates has been developed. This method enables the facile synthesis of functional phosphates such as alkyl phosphates, aza phosphates, thiophosphate, and mixed diaryl phosphates. A transient phosphorylpyridin-1-ium species in situ generated from phosphates with Tf2O/pyridine readily undergoes a substitution reaction with diverse nucleophiles to form versatile phosphate compounds.
Fe3O4@MgO nanoparticles as an efficient recyclable catalyst for the synthesis of phosphoroamidates via the Atherton-Todd reaction Dedicated to Professor Tsutomu Yokomatsu from Tokyo University of Pharmacy and Life Sciences on the occasion of his 65th birthday

A simple and efficient method is presented for the synthesis of phosphoroamidates in moderate to good yield via the Atherton-Todd coupling of primary amines with H-dialkyl phosphites using Fe3O4@MgO nanoparticles as a recyclable catalyst.

Copper-catalyzed stereospecific oxidative dehydrocouplings of P(O)H bonds with amines under air took place effi-ciently at room temperature to afford the corresponding amidophosphorus compounds in high yields. Mechanistic studies showed that this dehydroc
New benzotriazole-based reagents for the phosphonylation of various N-, O-, and S-nucleophiles
Panmand, Deepak S.,Tiwari, Anand D.,Panda, Siva S.,Monbaliu, Jean-Christophe M.,Beagle, Lucas K.,Asiri, Abdullah M.,Stevens, Christian V.,Steel, Peter J.,Hall, C. Dennis,Katritzky, Alan R.

Benzotriazole surrogates showing higher stabilities than the corresponding chlorophosphates, allow phosphonylation of a variety of N-, O-, and S-nucleophiles in good yields.
Phosphoramidate synthesis via copper-catalysed aerobic oxidative coupling of amines and H-phosphonates
Fraser, Jamie,Wilson, Laura J.,Blundell, Rebecca K.,Hayes, Christopher J.
supporting information, p. 8919 - 8921 (2013/09/24)
The copper-catalysed oxidative coupling of amines and H-phosphonates to produce phosphoramidates has been achieved using CuI as the catalyst and O 2 (present in air) as the sole oxidant.
Trichlorocyanuric acid: An efficient reagent for one-pot synthesis of Ptychodiscus brevis (PB-1) toxin and its derivatives
Gupta, Arvind K.,Acharya, Jyotiranjan,Dubey, Devendra K.,Kaushik, Mahabir P.
, p. 29 - 33 (2008/02/02)
Trichlorocyanuric acid is an efficient regent for simple and one-pot synthesis of dialkyl, N-cycloctylphosphoraamidates (PB-1) and its various derivatives in excellent yields. The procedure is operationally simple and involves the reaction of various dialkylphosphites with trichloroisocyanuric acid in acetonitrile and subsequent treatment with amines in presence KF-celite to give PB-1 and derivatives.
New route to O,O-diethyl phosphorocyanidate
Lopusinski, Andrzej
, p. 395 - 397 (2007/10/03)
A new and efficient route for synthesis of O, O-Diethyl Phosphorocyanidate by decomposition of diethyl phosphoryl-1,2,4,-dithiazolin-5-one was discussed. The use of phosphorocyanidates as coupling reagents in peptide chemistry and other applications of these compounds in organic synthesis was also demonstrated. It was found that these compounds were relatively unstable and could decompose easily, especially in the presence of water with the formation of hydrogen cyanide. A new efficient route to O, O-dialkyl phosphorocyamidates was offered, which were not contaminated by isomeric isocyanidates and could be used as the substrates for further synthetic purposes.
