METHOD FOR THE ESTERIFICATION OF P-O COMPONENTS
-
Paragraph 0038-0042, (2013/04/25)
The present invention is directed to a new method for esterification of P-O components. More specifically, the present invention relates to a new method for esterification of P-O components containing at least one P-O-H functional group, whereby the P-O-H functional group(s) is converted into P-O-R functional group(s). The method according tothe invention may find particular use in the manufacture of diesters of phosphorous acid.
Catalytic vapour-phase hydrolysis and photocatalytic oxidation of dimethyl methylphosphonate on a TiO2 surface
Trubitsyn, Dmitry A.,Vorontsov, Alexander V.
, p. 197 - 199 (2007/10/03)
The products of dimethyl methylphosphonate (DMMP) hydrolysis and photocatalytic oxidation on TiO2 were identified and quantified by a FTIR technique at different relative air humidities and concentrations of DMMP.
Oxidation in organophosphorus chemistry: Potassium peroxymonosulphate
Wozniak, Lucyna A.,Stec, Wojciech J.
, p. 2637 - 2640 (2007/10/03)
Potassium peroxymonosulphate (Oxone) is used as an efficient, chemoselective and stereoselective oxidizing agent for a wide variety of phosphorous, phosphothio- and phosphoseleno-compounds.
A FACILE SYNTHESIS OF TRIALKYLSILYLPHOSPHITES AND PHOSPHATES
Li, Zhonghua,Zhu, Chuanfang,Zhao, Yongzhen
, p. 229 - 232 (2007/10/02)
Trialkylsilylphosphites (1a-1d) and trialkylsilylphosphates (2a-2d) were synthesized in good yield by a facile method.The method could be easily used to prepare P-O-Si bond and P-Si bond compounds from dialkylphosphites and trialkylchlorosilanes.Key words: Phosphates; trialkylsilylphosphites; trialkylchlorosilanes.

DISPLACEMENT RATE OF ARYLOXY SUBSTITUENTS IN CYCLIC AND ACYCLIC TRIPHOSPHITES BY METHOXIDE IONS, AND WATER
Aksnes, Gunnar,Froeyen, Paul
, p. 45 - 50 (2007/10/02)
The displacement rate of aryloxy substituents by methoxide ions in the following triphosphites: 2-phenoxy-1,3,2-dioxaphospholane (I), 2-methoxy-benz-1,3,2-dioxaphospholene (II), and dimethyl phenylphosphite (III), is for each phosphite higher in methanol than in dichloromethane.On the other hand, dichloromethane discriminates much more strongly between five-membered cyclic and acyclic phosphites than methanol, as shown by the following rate ratios cyclic/acyclic in CH3OH: I/III = 13, II/III = 2; and in CH2Cl2: I/III = 1.8 x 103, II/III = 1.1 x 103. Water, as nucleophile towards the same phosphites in deuteroacetone, appears to exhibit somewhat similar magnitude of discrimination as methoxide in methanol. Key Words: Cyclic and acyclic triphosphites; displacement rate of aryloxy substituents.

ORGANOPHOSPHORUS CHEMISTRY. 2. THE REDUCTION OF QUINQUEVALENT PHOSPHORUS TO THE TRIVALENT STATE
Engel, Robert,Chakraborty, Subir
, p. 665 - 670 (2007/10/02)
Phosphoryl and phosphonyl chlorides are reduced conveniently to the monobasic acid forms of the corresponding phosphorous and phosphonous acids by the use of sodium borohydride dispersed in dioxane.
Process for the preparation of N-phosphonomethyl-glycine
-
, (2008/06/13)
N-phosphonomethylglycine is prepared from glycine and parsformaldehyde to obtain an intermediate which is reacted with dialkylphosphite to obtain an ester of the desired compound which is then hydrolyzed.
