Title (EN) CYCLOOCTATETRAENE COMPOUND
(FR) COMPOSE DE CYCLOOCTATETRAENE
Abstract:
(EN) Metal complex containing a transition metal from groups 4-6 of the Periodic System of the Elements or a lanthanide and at least one cyclooctatetraene ligand, characterized in that the metal complex contains as a ligand at least one cyclooctatetraene compound according to the formula (I): (R'nDR)a-COT-(RUn)b where COT = a cyclooctatetraene, (C8R'8-a-b); R = a linking group between COT and the DR'n group or the Un group; D = an electron-donating heteroatom chosen from group 15 or group 16 of the Periodic System of the Elements; Un = an unsaturated hydrocarbon group; R' = a substituent; n = the number of times that R' occurs bonded to D; a = the number of R'nDR groups; and b = the number of Un groups, with 1$m(F)a+b$m(F)8.
(FR) Complexe métallique contenant un métal de transition provenant des groupes 4-6 du système périodique des éléments ou un lanthanide et au moins un ligand de cyclooctatétraène, caractérisé par le fait que ce complexe métallique contient en tant que ligand au moins un composé de cyclooctatétraène représenté par la formule (I): (R'nDR)a-COT-(RUn)b dans laquelle: COT représente un cyclooctatétraène, (C8R'8-a-b); R représente un groupe de liaison entre COT et le groupe DR'n ou le groupe Un; D représente un hétéroatome donneur d'électrons sélectionné dans le groupe 15 ou le groupe 16 du système périodique des éléments; Un représente un groupe hydrocarbure insaturé; R' représente un substituant; n représente le nombre de fois que R' apparaît fixé à D; a est le nombre de groupes R'nDR; et b est le nombre de groupes Un, 1$m(F)a+b$m(F)8.
