Bunyan, P. J. published the artcileReactivity of organophosphorus compounds. XIII. Radical-chain transfer reactions of triethyl phosphite: a new phosphorothiolate synthesis, Product Details of C5H10Cl3O3P, the publication is Journal of the Chemical Society (1962), 2953-8, database is CAplus.
cf. CA 57, 4577c. Reinvestigation of the reaction between BrCCl3 and tri-Et phosphite has revealed the formation of CCl4 as a main product; reaction in the presence of BuSH gave S-Bu di-Et phosphorothioate in excellent yield. These and related reactions are discussed in terms of a radical-chain mechanism.
Journal of the Chemical Society published new progress about 866-23-9. 866-23-9 belongs to chlorides-buliding-blocks, auxiliary class Aliphatic Chain, name is Diethyltrichloromethylphosphonate, and the molecular formula is C5H10Cl3O3P, Product Details of C5H10Cl3O3P.
