Albrecht, S. published the artcileReactions of chloro-substituted methanephosphonic acid dialkyl esters with dialkyl phosphites, trialkyl phosphites, or alcohol/sodium alcoholate, Quality Control of 866-23-9, the publication is Zeitschrift fuer Anorganische und Allgemeine Chemie (1986), 207-11, database is CAplus.
(RO)2P(O)CCl3 (R = Et, Bu) react with dialkyl phosphites and alc. in the presence of tertiary amines or with trialkyl phosphites and alc. yielding diesters of dichloromethanephosphonic acids and triesters of phosphoric acid. When esters of trichloromethane- or dichloromethanephosphonic acid react with alcs. in the presence of sodium alcoholates, a quant. cleavage of P-C bond occurs, and triesters of phosphoric acid and CHCl3 or CH2Cl2 are formed.
