Abstract
The title compound [Fe2(CO)6(mu-Ph2N2)] (1) Was obtained in a two-step sequence from Fe2(CO)9 and phenyl azide via the intermediate tetraaza diene complex (CO)3Fe . Ph2N4 (2b). Its N-N bond length (1.41 angstrom ) is 0.04 angstrom longer than that in [Fe2(CO)6(mu-Et2N2)] correspond ing to an enhanced reactivity. Accordingly, the reactions of 1 with CO and H-2 which lead to [Fe2(CO)6(mu-PhN-CO-NPh)] (4) and [Fe2(CO)6(mu- NHPh)2] (5) respectively, involve cleavage of the N-N bond.
