A compound comprising at least one cyclic amine, having an organolithium side-chain, defined according to formula (I) (see fig. I) wherein Z is a lithium atom (Li); R1 is selected from the group consisting of organic groups containing from 1 to about 12 carbon atoms and a bridging bond; each R2 is independently selected from the group consisting of hydrogen, organicgroups containing from 1 to about 12 carbon atoms, and a bridging bond; each R3 is independently selected from the group consisting of hydrogen and organic groups containing from 1 to about 12 carbon atoms; a is an integer from 4 to about 16; and b is an integer from 0 to about 12; and optionally including a bridge, formed by the selection of two of said bridging bonds, the bridge having0 to about 6 carbon atoms between the bridging ring members.

Un composé comprenant au moins une amine cyclique, ayant une chaîne latérale organolithium, conforme à la formule I) (voir la fig. I) où Z est un atome de lithium (Li); R1 est choisi parmi un groupe constitué de groupements organiques contenant de 1 à environ 12 atomes de carbone et un lien formant un pont; chacun des groupes R2 est choisi de façon indépendante parmi un groupe constitué de l'hydrogène, de groupements organiques contenant de 1 à environ 12 atomes de carbone et un lien formant un pont; chacun des groupe R3 est choisi de façon indépendante parmi un groupe constitué de l'hydrogène et de groupements organiques contenant de 1 à environ 12 atomes de carbone, a est un entier de 4 à environ 16 et b est un entier de 0 à environ 12, qui peut comporter un pont formé par la sélection de deux desdits liens de pontage, ce pont ayant de 0 à environ 6 atomes de carbone entre les éléments de l'anneau de pontage 0
