2768-31-2

BENZYL DIETHYL PHOSPHITE is a chemical compound with the molecular formula C11H17O3P. It features a benzyl group attached to a phosphite group with two ethyl side chains. This clear, colorless liquid is widely used in the chemical industry as an intermediate in the manufacturing of other chemicals. It can react vigorously with oxidizing materials and may cause irritation upon contact with skin and eyes or inhalation, leading to respiratory tract irritation. Proper storage requires a cool, dry, well-ventilated area away from sources of ignition.

Check Digit Verification of cas no

The CAS Registry Mumber 2768-31-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,6 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2768-31:
(6*2)+(5*7)+(4*6)+(3*8)+(2*3)+(1*1)=102
102 % 10 = 2
So 2768-31-2 is a valid CAS Registry Number.

Alcohol-based Michaelis-Arbuzov reaction: An efficient and environmentally-benign method for C-P(O) bond formation

Ma, Xiantao,Xu, Qing,Li, Huan,Su, Chenliang,Yu, Lei,Zhang, Xu,Cao, Hongen,Han, Li-Biao

supporting information, p. 3408 - 3413 (2018/08/06)

The famous Michaelis-Arbuzov reaction is extensively used both in the laboratory and industry to manufacture tons of widely-used organophosphoryl compounds every year. However, this method and the modified Michaelis-Arbuzov reactions developed recently still have some limitations. We now report a new alcohol-version of the Michaelis-Arbuzov reaction that can provide an efficient and environmentally-benign method to address the problems of the known Michaelis-Arbuzov reactions. That is, a wide range of alcohols can readily react with phosphites, phosphonites, and phosphinites to give all the three kinds of phosphoryl compounds (phosphonates, phosphinates, and phosphine oxides) using an n-Bu4NI-catalyzed efficient C-P(O) bond formation reaction. This general method can also be easily scaled up and used for further synthetic transformations in one pot.

Phosphitylation via the Mitsunobu reaction

Grice, I. Darren,Harvey, Peta J.,Jenkins, Ian D.,Gallagher, Michael J.,Ranasinghe, Millagahamada G.

, p. 1087 - 1090 (2007/10/03)

Treatment of a dialkyl phosphite with triphenylphosphine and diisopropyl azodicarboxylate in toluene, followed by addition of an alcohol, results in the formation of the corresponding trialkyl phosphite. Similarly, dialkyl phosphonites can be synthesised from monoalkyl phosphites (alkyl phosphinates).

A New Phosphorylation Method via O-Diethylboryl Intermediates

Dahlhoff, Wilhelm V.,Taba, Kalulu M.

, p. 1260 - 1262 (2007/10/02)

Diphenylchlorophosphine and diethylchlorophosphite react with acetylacetone to generate intermediate phosphine enolates 3 which are quenched with O-diethylboryl derivatives and then oxidized with hydrogen peroxide to give diphenylphosphinates 4 and diethylphosphates 5. - Keywords: Phosphorylation, Diphenylphosphinates, Diethylphosphates, O-Diethylboryl Intermediates
