η2-Benzyne and η1-benzylidene complexes of niobium with ancillary imido ligands
Abstract
Rare η2-benzyne and benzylidene complexes of niobium have been synthesised from [Nb(C5R5)(NR′)Cl2](R = H, Me; R′= 2,6-Pri2C6H3)via intermediate diphenyl and dibenzyl species and their molecular structures have been determined: these complexes are analogues of well-established zirconocene derivatives.
