(EN) PREPARATION OF MONOFLUOROALKENES
(FR) PREPARATION DE MONOFLUOROALCENES
Abstract
(EN)
There is described a process for the preparation of compounds of formula (I) in which R is hydrogen, optionally substituted alkyl, optionally substituted alkenyl optionally substituted cycloalkyl, optionally substituted phenyl or optionally substituted heterocyclyl, and R1 and R2 are hydrogen, an organic radical or together with the ring to which they are attached, form an optionally substituted ring, which may contain one or more hetero atoms, which comprises reacting a compound of formula (II) with a compound of formula (III) in which the ring Q is an optionally substituted heteroaromatic ring, which optionally comprises one or more further hetero atoms and to which is optionally fused an optionally substituted ring.
(FR)
L'invention concerne un procédé de préparation de composés de la formule (I), dans laquelle R représente hydrogène, un alkyle éventuellement substitué, un alcényle éventuellement substitué, un cycloalkyle éventuellement substitué, un phényle éventuellement substitué ou un hétérocyclyle éventuellement substitué, et R1 et R2 représentent hydrogène, un radical organique ou forment ensemble, avec le cycle auquel ils appartiennent, un cycle éventuellement substitué qui peut contenir un ou plusieurs hétéroatomes. Ce procédé consiste à faire réagir un composé de la formule (II) avec un composé de la formule (III), dans laquelle le cycle Q représente un cycle hétéroaromatique éventuellement substitué, qui comporte éventuellement un ou plusieurs hétéroatomes, et avec lequel est éventuellement fusionné un cycle éventuellement substitué.
