标 题:Reagent and process for the synthesis of oxysulphide-containing fluorine-containing organic derivatives
发明人：FORAT GERARD; MAS JEAN-MANUEL; SAINT-JALMES LAURENT
权利人:RHONE POULENC CHIMIE
摘要:The invention relates to a reagent which is useful for the synthesis of oxysulphide-containing fluorine-containing organic derivatives by reacting with an oxide of sulphur, especially sulphur dioxide, characterized in that it comprises: a) a fluorocarboxylic acid of formula Ew-CF2-COOH where Ew is an electron-withdrawing group or atom which is at least partially salified by an organic or inorganic cation, and b) an aprotic polar solvent; and in that the content of releasable protons carried by its various components, including their impurities, is at most equal to half the initial molar concentration of the said fluorocarboxylic acid. This reagent can be used by heating in order to form fluorine-containing sulphinic or sulphonic acids.

标题 :Allyl esters substituted by a difluoromethylene group, their process of synthesis and their use, and a process for functionalizing a double bond
发明人：ROQUES NICOLAS
权利人:RHODIA CHIMIE SA
摘要:This invention provides compounds of formula: n n n in which R f is a radical that carries a perfluoromethylene group, which group ensures bonding to the remainder of the molecule; R1 and R3, which can be the same or different, are chosen from among hydrogen and alkyl or aryl radicals; Ψ is an electroattractor group such that Ψ-O—H is an acid whose pKa (in water) is at most equal to 8, advantageously 6, and preferably 5. These compounds are useful for the synthesis of nitrogen-containing heterocyclic compounds.
