18855-52-2 Usage

Uses

Tetraethyl (dimethylaminomethylene)diphosphonate undergoes Horner-Wadsworth-Emmons olefination with an aldehyde gives the ?-phosphonato enamine, readily convertible to the homologous acid.

Check Digit Verification of cas no

The CAS Registry Mumber 18855-52-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,5 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18855-52:
(7*1)+(6*8)+(5*8)+(4*5)+(3*5)+(2*5)+(1*2)=142
142 % 10 = 2
So 18855-52-2 is a valid CAS Registry Number.

Optimization, continuation and lack of the one-step diphosphorylation reaction. Assay of modification of the tetraethyl-(pyrrolidine-2,2-diyl)bisphosphonate

Olive, Gilles,Jacques, Alain

, p. 33 - 46 (2003)

The optimization of the one-step diphosphorylation reaction is reported. The synthesis of new α-aminobisphosphonates with four- and six-membered rings and acyclic species with several substituents on the nitrogen atom and on the carbon atom bearing the two phosphorus atoms is described.

The invention relates to quaternary ammonium multi-dentate mono-, bis-, tris- and tetrakis-phosphonate compounds, processes for preparing quaternary ammonium multi-dentate mono-, bis-, tris- and tetrakis-phosphonate compounds, antimicrobial coating compositions comprising quaternary ammonium multi-dentate mono-, bis-, tris- and tetrakis-phosphonate compounds and method of treating a surface with said compositions to provide a durable, antimicrobial-treated surface.

Synthesis of the new types of N-substituted aminomethylenebisorganophosphorus acids and their derivatives

Prishchenko, Andrey A.,Livantsov, Mikhail V.,Novikova, Olga P.,Livantsova, Ludmila I.,Petrosyan, Valery S.

experimental part, p. 319 - 324 (2010/08/05)

The interaction of esters of trivalent organophosphorus acids containing PH and POSiMe3 fragments with various derivatives of formamide is proposed as convenient methods for the synthesis of new N-substituted aminomethylenebisorganophos-phorus acids and their derivatives with three-, four-, and five-coordinated phosphorus. Also the new functionalized derivatives of the new aminomethylenebisphosphinic acids with substituted hydroxymethyl moieties are synthesized, and some properties of the obtained compounds are presented.
