Title (EN) NOVEL RUTHENIUM COMPLEXES AND THEIR USES IN PROCESSES FOR FORMATION AND/OR HYDROGENATION OF ESTERS, AMIDES AND DERIVATIVES THEREOF
(FR) NOUVEAUX COMPLEXES DE RUTHÉNIUM ET LEURS UTILISATIONS DANS DES PROCÉDÉS DE PRÉPARATION ET/OU D'HYDROGÉNATION D'ESTERS, D'AMIDES ET DE LEURS DÉRIVÉS
Abstract: front page image
(EN)The present invention relates to novel Ruthenium complexes and related borohydride complexes, and their use for (1) hydrogenation of amides (including polyamides) to alcohols and amines; (2) preparing amides from alcohols with amines (including preparing polyamides (e.g., polypeptides) by reacting dialcohols and diamines or by polymerization of amino alcohols); (3) hydrogenation of esters to alcohols (including hydrogenation of cyclic esters (lactones), cyclic di-esters (di-lactones) or polyesters); (4) hydrogenation of organic carbonates (including polycarbonates) to alcohols and of carbamates (including polycarbamates) or urea derivatives to alcohols and amines; (5) dehydrogenative coupling of alcohols to esters; (6) hydrogenation of secondary alcohols to ketones; (7) amidation of esters (synthesis of amides from esters and amines); (8) acylation of alcohols using esters; (9) coupling of alcohols with water to form carboxylic acids; and (10) dehydrogenation of beta- amino alcohols to form pyrazines. The present invention further relates to novel uses of certain pyridine Ruthenium complexes.
(FR)L'invention concerne de nouveaux catalyseurs du ruthénium et des complexes apparentés de borohydrure. Elle concerne l'utilisation de tels catalyseurs, entre autres, pour 1) l'hydrogénation d'amides (y compris des polyamides) en alcools et en amines; 2) la préparation d'amides à partir d'alcools avec des amines (notamment la préparation de polyamides (des polypeptides, par exemple) par mise en réaction de dialcools et de diamines et/ou par polymérisation d'amino-alcools); 3) l'hydrogénation d'esters en alcools (y compris l'hydrogénation d'esters cycliques (lactones) ou de diesters cycliques (dilactones) ou de polyesters); 4) l'hydrogénation de carbonates organiques (y compris des polycarbonates) en alcools, et l'hydrogénation de carbamates (y compris des polycarbamates) ou de dérivés d'urée en alcools et en amines; 5) le couplage déshydrogénatif d'alcools en esters; 6) l'hydrogénation d'alcools secondaires en cétones; 7) l'amidation d'esters (c'est-à-dire la synthèse d'amides à partir d'esters et d'amines); 8) l'acylation d'alcools à l'aide d'esters; 9) le couplage d'alcools avec de l'eau pour former des acides carboxyliques; et 10) la déshydrogénation de beta-amino alcools pour former des pyrazines. L'invention concerne en outre de nouvelles utilisations de certains catalyseurs du ruthénium, tels que la pyridine.
