Title
(EN) THE ALKOXYLATION OF HETEROCYCLIC COMPOUNDS IN THE PRESENCE OF FLUORINE
(FR) ALCOXYLATION DE COMPOSES HETEROCYCLIQUES EN PRESENCE DE FLUOR
Abstract
(EN)
A method for introducing a functionalising group as a ring substituent into a nitrogen-containing heterocyclic aromatic compound which method comprises reacting a compound containing the functionalising group with the heterocyclic aromatic compound in the presence of elemental fluorine. The functionalising group may be a group -ROH or a group -Sra or a group -NRbRc wherein R, Ra, Rb and Rc are each independently selected from the following groups which may be optionally substituted: alkyl, allyl, alkoxy, acyl, acyloxy, cycloalkyl and aryl.
(FR)
Procédé d'introduction d'un groupe fonctionnalisant sous forme d'un substituant de cycle dans un composé aromatique hétérocyclique contant de l'azote. Ce procédé consiste à faire réagir un composé contenant le groupe fonctionnalisant avec le composé aromatique hétéroxyclique en présence de fluor élémentaire. Le groupe fonctionnalisant peut être un groupe -ROH ou un groupe -Sra ou encore un groupe -NRbRc dans lesquels R, Ra, Rb et Rc sont indépendamment sélectionnés dans les groupes suivants qui peuvent être facultativement substitués: alkyle, allyle, alcoxy, acyle, acyloxy, cycloalkyle et aryle.
