Phosphorodichloridates esters

Several of these steroid derivatives underwent elimination of phosphorodichloridate anion, giving hydrocarbon products, rather than ester formation when treated with methanolic pyridine. Pyrophosphoric acid itself has been used to phosphorylate (2-hydroxymethyl)pyridine. ... [Pg.97]

Phosphorus oxychloride is a suitable reagent for preparation of the symmetrically substituted phospho-triesters of type (RO)3PO. The preparation is easily achieved by treatment of phosphorus oxychloride with 3 equiv. of alcohols or their metal salts. The reaction is generally promoted by a base or acid. Titanium trichloride is a particularly effective catalyst for the reaction. Conversion of POCI3 to unsymmetri-cally substituted phosphotriesters is achievable with difficulty. Phosphorochloridates and phosphorodichloridates have been used for the preparation of mixed tertiary phosphoric esters of type (ROlmPOfOROn (ffi = 1, n = 2, or m = 2, n = 1) in a very wide variety. Reaction of phosphorus oxychloride and 1 or 2 equiv. of alcohols followed by hydrolysis forms phosphomonoesters or phosphodi-esters, respectively. The hydrolysis may be generally effected by dilute aqueous alkali. Some phosphoFodichlori te intermediates are easily hydrolyzed by water. For example, the phosphorylation of a ribonucleoside (1 equation 4) with phosphorus oxychloride in an aqueous pyridine-acetonitrile mixture furnishes the nucleoside S -monophosphate (2) in excellent yield. ...

A remarkable demonstration of the ease of formation of six-co-ordinate species from four-co-ordinate precursors is the observation that both phenyl phosphorodichloridate and the cyclic ester (33) give the salt (34) when treated... [Pg.106]

JO Sulfur and Selenium Containing Compounds. - The interaction of 0,0-dialkyl methylphosphonothioates acid with POCI3 to give the chloridates (286) and alkyl phosphorodichloridates parallels reactions of thiophosphoric esters already encountered. The use of Lawesson s reagent to replace the phosphoryl bond in (l,l-difluoroalkyl)phosphonic esters by thiophosphoryl, has been noted (see also reference 258). - ... [Pg.143]

The preparation of furyl phosphorodichloridate is based upon a method to prepare 2-chlorofuran (161 yield, Hormi, Nasman unpublished). Later the preparation was extended to a general method to prepare furyl esters from carboxylic acid chlorides lacking a-hydrogens and alkyl furyl carbonates from primary (other than methyl) and secondary alkyl chloroformates. Phosphoryl chloride was the only acid chloride except carbon analogues found to give a furyl ester by the amine-catalyzed reaction. [Pg.171]
