In one embodiment, the invention provides a polymer comprising imidazole ring units having nitrogen at the 1 and 3 positions of the ring; a carbon at each of the 2, 4 and 5 positions of the ring; and radical substituents G1 and G2 carried at the 4 and 5 positions. G1 and G2 are each independently selected from cyano, sustituents derived from cyano, and substituents which replace cyano. The polymers formed by at least two of the cyclic imidazole units. In another embodiment, the invention provides new imidazole compounds usable as monomers to form the polymers. In still another embodiment, the invention provides a method for using the polymers as a coupling/activator for synthon synthesis.
Dans un mode de réalisation, l'invention concerne un polymère comprenant des unités sous forme de noyau d'imidazole comportant de l'azote en positions 1 et 3; un carbone en positions 2, 4 et 5; et des radicaux substitutifs G1 et G2 en positions 4 et 5. G1 et G2 sont chacun indépendamment choisis parmi cyano, des substituants dérivés de cyano et des substituants de cyano. Les polymères sont formés par au moins deux des unités sous forme de noyau d'imidazole. Dans un autre mode de réalisation, l'invention concerne de nouveaux composés d'imidazole pouvant être utilisés comme monomères pour former les polymères. Dans un autre mode de réalisation, l'invention concerne un procédé permettant d'utiliser les polymères comme activateurs de couplage pour la synthèse de synthons.
