The present disclosure re-lates to processes and methods of gener-ating hydrogen via the dehydrocoupling of amine boranes using ligand-stabilized homogenous metal catalysts. The amine--borane is shown by the formula (I), R1R2N-BHR3R4. A process is also shown for the preparation of a linear, branched or cyclic polymer which comprises a re-peating unit of the formula (II), --[R1R2N-BR3R4]-n, by reacting HR1R2N--BHR3R4 in the presence of at least one ligand-stabilized metal catalyst.
La présente invention concerne des processus et des procédés destinés à générer de lhydrogène par déhydrocouplage damine-boranes utilisant des catalyseurs métalliques homogènes stabilisés aux ligands. L'amine-borane est représenté par la formule (I), R1R2N-BHR3R. L'invention concerne en outre un procédé de préparation d'un polymère linéaire, ramifié ou cyclique qui comprend une unité récurrente de la formule (II), - [R1R2N-BR3R4] -n, par mise en réaction de HR1R2N-BHR3R4 en présence d'au moins un catalyseur métallique stabilisé aux ligands.
