Title (EN) IRON-CATALYZED CROSS-COUPLING OF METHANOL WITH SECONDARY OR TERTIARY ALCOHOLS TO PRODUCE FORMATE ESTERS
(FR) COUPLAGE CROISÉ CATALYSÉ PAR DU FER DE MÉTHANOL À L'AIDE D'ALCOOLS SECONDAIRES OU TERTIAIRES POUR PRODUIRE DES ESTERS DE FORMIATE
Abstract:
(EN) A process for preparing a variety of secondary and tertiary alkyl formate esters via the coupling of methanol and secondary (or tertiary) alcohols. Iron-based catalysts, supported by pincer ligands, are employed to produce these formate esters in high yields and unprecedentedly high selectivities (>99%). Remarkably, the coupling strategy is also applicable to bulkier tertiary alcohols, which afford corresponding tertiary formate esters in moderately high yields and high selectivities.
(FR) L'invention concerne également un procédé de préparation d'une variété d'esters de formiate d'alkyle secondaires et tertiaires par l'intermédiaire du couplage de méthanol et d'alcools secondaires (ou tertiaires). La présente invention permet d'utiliser des catalyseurs à base de fer supportés par des ligands pinces, pour produire des esters de formiate à haut rendement et des sélectivités élevées sans précédent (> 99 %). De façon remarquable, la stratégie de couplage est également applicable à des alcools tertiaires plus volumineux, qui permettent d'obtenir des esters de formiate tertiaires correspondants dans des rendements modérément élevés et des sélectivités élevées.
