The compounds are obtained by a method which consists in preparing an amine-borane R1R2NH.BH3 complex, in transforming it into aminoborane R1R2NBH2 by heating, then in reacting it with an A-X compound wherein X is a leaving group.Type: GrantFiled: December 20, 2002Date of Patent: February 20, 2007Assignees: Centre National de la Recherche Scientifique, Universite de RennesInventors: Michel Vaultier, Gilles Alcaraz, Christophe Duriez, Lisenn Euzenat, Yann Ribourdouille
