Abstract
- [MoO2(acac)2] (acac=acetylacetonate) promotes the disproportionation of hydrazine in THF solutions. The active catalytic species, [MoVIO2]2+, are produced according to the reaction: [MoO2(C5H7O2)2]+2N2H4 →[MoO2]2+ +2C5H8N2 +2OH− +2H2O. The main product of the reduction of hydrazine is ammonia while 3,5-dimethylpyrazole (C5H8N2) was isolated as a side-product. A catalytic cycle was proposed and the probable reaction intermediate is a hydrazido-complex, [MoIV=NNH2(OH2)2]2+. The intermediate species, [MoVIO2NH3]2+ reacts with hydroxide ion leading to the complex cis-[MoVIO2(OH)2(NH3)], which was isolated and characterized. [Copyright &y& Elsevier]
