摘要：
The novel d2 niobium nitrene complex (eta-C5Me5)Nb(NAr)(PMe3), (Ar = 2,6-(i)Pr2C6H3) (1) is accessible via magnesium reduction of (eta-C5Me5)Nb(NAr)Cl2 in the presence of PMe3. Compound 1 reacts with carbon monoxide, ethylene and diphenylacetylene to give adducts of the type (eta-C5Me5)Nb(NAr)(PMe3)(L) (L = CO, C2H4, PhC = CPh) and is oxidised by dihydrogen to (eta-C5Me5)Nb(NAr)(PMe3)(H)2.
