Abstract: front page image
(EN)A non-symmetrical diphosphine of the formula R?1¿R?2¿P-(Z)-PR?3¿R?4¿ wherein Z represents a chain of 2 to 4 carbon atoms which may be substituted, which chain may be saturated or unsaturated, and R?1¿, R?2¿, R?3¿ and R?4¿, which may be the same or different, are aliphatic, aromatic or heteroaromatic groups attached to the phosphorus by carbon, nitrogen, oxygen or sulphur such that each phosphorus atom and its substituents independently form a single enantiomer.
(FR)L'invention concerne une diphosphine non symétrique de formule R?1¿R?2¿P-(Z)-PR?3¿R?4¿ dans laquelle Z représente une chaîne de 2 à 4 atomes de carbone saturée ou non, pouvant être substituée, et où R?1¿, R?2¿, R?3¿ et R?4¿, qui peuvent être identiques ou différents, représentent des groupes aliphatiques, aromatiques ou hétéroaromatiques liés au phosphore par le carbone, l'azote, l'oxygène ou le soufre, de telle manière que chaque atome de phosphore et ses substituants forment indépendamment un énantiomère unique.
