(FR) PROCEDE DE PREPARATION ET PROCEDE DE SEPARATION DE DERIVES DE 2,4'-DIPYRIDYLE ET PROCEDES DE PREPARATION DE DERIVES DE BENZOXAZEPINE ET LEURS SELS
Abstract:
(EN) A method of production of 2,4'-dipyridyl derivatives by a cross coupling reaction of a 2-halopyridine derivative and a 4-halopyridine using a nickel complex catalyst and a method of separation of a 2,4'-dipyridyl derivative from a mixture of dipyridyl isomers containing a 2,2'-dipyridyl derivative, 2,4'-dipyridyl derivative, and 4,4'-dipyridyl by using a dilute aqueous copper sulfate solution to insolubilize and remove the 2,2'-dipyridyl derivative and 4,4'-dipyridyl is disclosed.
(FR) Procédé de préparation de dérivés de 2,4'-dipyridyle au moyen d'une réaction de couplage croisé d'un dérivé de 2-halopyridine et d'une 4-halopyridine mettant en application un catalyseur de complexe de nickel et procédé de séparation d'un dérivé de 2,4'-dipyridyle depuis un mélange d'isomères de dipyridyle contenant un dérivé de 2,2'-dipyridyle, un dérivé de 2,4'-dipyridyle et 4,4'-dipyridyle, consistant à utiliser une solution de sulfate de cuivre afin d'insolubiliser et d'extraire le dérivé de 2,2'-dipyridyle, ainsi que 4,4'-dipyridyle.
