Abstract: front page image
(EN)Chiral diphosphines, diphosphinites, diphosphites and diphosphonites derived from (Z)-2-butenes suitable to act as chiral ligands, complexes between said diphosphines, diphosphinites, diphosphites and diphosphonites and transition metals, and their utilization as chiral catalysts in stereocontrolled reactions, such as diastereo- and enantioselective reduction reactions, diastereo- and enantioselective hydroformylation reactions, diastereo- and enantioselective hydro cyanation reactions. Process for the preparation of said chiral diphosphines, diphosphinites, diphosphites and diphosphonites and process for the preparation of said complexes and for their utilization in stereocontrolled reactions.
(FR)La présente invention concerne des diphosphines, diphosphinites, diphosphites et diphosphonites chirales tirées de (Z)-2-butènes convenant comme ligands chiraux, des complexes entre ces diphosphines, diphosphinites, diphosphites et diphosphonites et des métaux de transition, et leur utilisation comme catalyseurs chiraux dans des réactions stéréo-contrôlées, telles que des réactions de réduction diastéréo- et énantio-sélectives, des réactions d'hydro-formylation diastéréo- et énantio-sélectives, et des réactions d'hydro-cyanation diastéréo- et énantio-sélectives. L'invention concerne enfin des procédés d'élaboration de ces diphosphines, diphosphinites, diphosphites et diphosphonites chirales, ainsi que des procédés permettant l'élaboration desdits complexes et leur utilisation dans des réactions stéréo-contrôlées.
