Abstract
Reaction of NbCl4(THF)(2) with 3 equiv of Cy(2)-NLi in toluene formed (Cy(2)N)(2)Nb(CyNC(6)H(10))Cl (1), where one cyclohexyl ring was metal ated to form a niobaaziridine ring. Further reaction of 1 with NaH-BEt (3) in toluene led to the formation. of the end-on dinitrogen, complex [(Cy(2)N)(3)Nb](2)(N-2), which was isolated as pale yellow crystals i n good yield.
