The present invention relates to a process for the production of hydrogen comprising contacting at least one complex of formula (I), wherein: X- is an anion; Y is N or CR6; M is selected from Ru, Os and Fe; each of A and B is independently a saturated, unsaturated or partially unsaturated carbocyclic ring; R5, R6 and R7 are each independently selected from H, NR24R25, C1-6-alkyl and C1-6-haloalkyl, or two or more of R5, R6 and R7 are linked, together with the carbons to which they are attached, to form a saturated or unsaturated carbocyclic group; R8-R25 are each independently selected from H, C1-6-alkyl, C1-6-haloalkyl and a linker group optionally attached to a solid support; with at least one substrate of formula (II), R1R2-NH-BH-R3R4 (II), wherein R1, R2, R3 and R4 are each independently selected from H, C1-20-alkyl, fluoro-substituted-C1-20-alkyl and C6-14-aryl, or any two of R1, R2, R3 and R4 are linked to form a C2-10-alkylene group, which together with the nitrogen and/or boron atoms to which they are attached, forms a cyclic group. Further aspects of the invention relate to a hydrogen generation system comprising a complex of formula (I), a substrate of formula (II) and a solvent, and to the use of complexes of formula (I) in fuel cells. Another aspect of the invention relates to novel complexes of formula (I). |
