Reactions of OsCl2(PPh3)3 (1) with bidentate nitrogen-based ligands at room temperature led to the formation of complexes OsCl2(PPh3)2(diamine) (2~6) and OsCl2(PPh3)2(Phen*) (7~11). Complexes 2~11 showed high activity in the catalytic dehydrogenation of ammonia borane at 60℃, in THF/DME (V:V=1:1.6) solution with the catalyst loading of 5 mol%. Among all the catalysts, compound 4 demonstrated the highest catalytic activity, which represents the most efficient osmium catalyst in catalytic dehydrogenation of ammonia borane until now.

Key words: osmium, complex, synthesis, catalytic dehydrogenation, ammonia borane
