Abstract

The new niobium imido complex [Nb(eta -C5H5){N(C6H3Me2-2,6)}Cl-2] 1* has been prepared. Its reactions with anionic reagents lead to a series of alkyl and amido derivatives [Nb(eta -C5H5){N(C6H3Me2-2,6)}MeCl] 2, [Nb(eta -C5H5){N(C6H3Me2-2,6)}{NH(C6H3Me2-2,6)}Cl] 3, [Nb(eta -C5H5){N(C6H3Me2-2,6)}{NH(C6H3Me2-2,6)}(2)] 4*, [Nb(eta -C5H5)(2){N(C6H3Me2-2,6)}Cl] 5, [Nb(eta -C5H5)(2){N(C6H3Me2-2,6)}Me] 6 and [Nb(eta -C5H5){N(C6H3Me2-2,6)}{NH(C6H3Me2-2,6)}Me] 7*. Variable temperature NMR studies on the amido complexes 3, 4 and 7 are reported (* indicates the crystal structure has been determined).
