| Abstract: | The mechanism of the transformation of (η5-C5H5)2NbCl2 to (η5-C5H5)2NbH3 by hydridoaluminate reducing agents has been investigated. Results suggest disproportionation of a niobium(IV) hydrite, leading to the trihydride product and a niobium(III) hydridoaluminate, (η5-C5H5)2NbH2AlR2, which in turn is converted to the trihydride on hydrolysis. (η5-C5H5)2NbH2AlH2 has been isolated; deuterium labelling shows that hydrogens exchange between ring and metal-bridging positions in this molecule. |
