Title (EN) A METHOD FOR THE PREPARATION OF DIAZOALKANES
(FR) PROCÉDÉ POUR LA PRÉPARATION DE DIAZOALCANES
Abstract: front page image
(EN)The present invention relates to a method of forming diazoalkanes. One aspect of the present invention provides a method for the production of a N-alkyl-N-nitroso compound from a starting material, comprising the use of a tribasic acid to acidify an amine. A second aspect of the present invention provides a method for the production of a diazoalkane, comprising reacting a N-alkyl-N-nitroso compound with a base and a phase transfer catalyst, wherein no organic solvent is used,
(FR)La présente invention concerne un procédé permettant de former des diazoalcanes. Un aspect de la présente invention concerne un procédé pour la production d'un composé N-alkyl-N-nitroso à partir d'un matériau de départ, comprenant l'utilisation d'un acide tribasique pour acidifier une amine. Un second aspect de la présente invention concerne un procédé pour la production d'un diazoalcane, comprenant la réaction d'un composé N-alkyl-N-nitroso avec une base et un catalyseur de transfert de phase, dans lequel aucun solvant organique n'est utilisé.
