Title (EN) RUTHENIUM COMPLEXES HAVING (P-P)-COORDINATED DISPHOSPHORUS DONOR LIGANDS AND PROCESSES FOR PREPARING THEM
(FR) COMPLEXES DU RUTHÉNIUM AYANT DES LIGANDS DONNEURS DIPHOSPHORES À COORDINATION P-P ET LEURS PROCÉDÉS DE FABRICATION
Abstract: front page image
(EN)The invention relates to ruthenium complexes which have a chiral diphosphorus donor ligand and in which the ruthenium has the oxidation state (+11) and the chiral diphosphorus donor ligand has bidentate P-P coordination to the ruthenium. The ruthenium complexes are present in two forms (cationic type A and uncharged type B), are cyclic and have a four- to six-membered ring incorporating the diphosphorus donor ligand. The chiral diphosphorus donor ligands are selected from the group consisting of diphosphines, diphospholanes, diphosphites, diphosphonites and diazaphospholanes. Furthermore, processes for preparing the ruthenium complexes of types A and B, which are based on ligand exchange reactions, are described. The Ru complexes are used as catalysts for homogeneous asymmetric catalysis for preparing organic compounds.
(FR)L'invention porte sur des complexes du ruthénium qui ont un ligand donneur diphosphore chiral et dans lesquels le ruthénium a l'état d'oxydation (+11) et le ligand donneur diphosphore chiral a une coordination P-P bidentate au ruthénium. Les complexes du ruthénium sont présents sous deux formes (type A cationique et type B non chargé), sont cycliques et ont un cycle à quatre à six chaînons incorporant le ligand donneur diphosphore. Les ligands donneurs diphosphores chiraux sont choisis dans le groupe constitué par les diphosphines, les diphospholanes, les diphosphites, les diphosphonites et les diazaphospholanes. De plus, l'invention porte sur des procédés de fabrication des complexes du ruthénium des types A et B, qui sont à base de réactions d'échange de ligand. Les complexes du Ru sont utilisés comme catalyseurs pour la catalyse asymétrique homogène pour préparer des composés organiques.
