Summary Ligating dinitrogen, in the complexes,trans-M(N2)2(Ph2PCH2CH2PPh2)2 (where M=Mo or W) may be acylated by trifluoroacetic anhydride, to give trifluoroacetyldiazenido complexes in high yield. Unlike corresponding reactions with acyl halides, trifluoroacetylation proceeds under nonradical conditions, and a mechanism analogous to that of protonation is suggested. Dinitrogen-derived ligands may also be acylated by (CF3CO)2O, so that the methyldiazenido ligand is converted into a methyl (trifluoroacetyl) hydrazido (2-) ligand, and the acetyldiazenido ligand undergoes transacylation to give a trifluoroacetyl diazenido derivative. New complexes were characterised by i.r.,19F and1H n.m.r. spectra, and by elemental analysis.
