Groups 5 and 6 terminal hydrazido(2-) complexes: Nβ substituent effects on ligand-to-metal charge-transfer energies and oxidation states

Brightly colored terminal hydrazido(2-) (dme)MCl3(NNR 2) (dme = 1,2-dimethoxyethane; M = Nb, Ta; R = alkyl, aryl) or (MeCN)WCl4(NNR2) complexes have been synthesized and characterized. Perturbing the electronic environment of the β (NR 2) nitrogen affects the energy of the lowest-energy charge-transfer (CT) transition in these complexes. For group 5 complexes, increasing the energy of the Nβ lone pair decreases the ligand-to-metal CT (LMCT) energy, except for electron-rich niobium dialkylhydrazides, which pyramidalize Nβ in order to reduce the overlap between the Nb=N α π bond and the Nβ lone pair. For W complexes, increasing the energy of Nβ eventually leads to reduction from formally [WVI≡N-NR2] with a hydrazido(2-) ligand to [WIV=N=NR2] with a neutral 1,1-diazene ligand. The photophysical properties of these complexes highlight the potential redox noninnocence of hydrazido ligands, which could lead to ligand- and/or metal-based redox chemistry in early transition metal derivatives.

EFFECT OF NATURE OF REAGENTS AND MEDIUM ON THE DIRECTION OF TRANSFORMATIONS OF RADICAL-CATIONS IN THE REACTION OF DIARYLAMINES WITH NITROSONIUM FLUOROBORATE

Diphenylamine and 4,4'-dimethoxydiphenylamine in acetonitrile undergo one-electron oxidation by NOBF4.The maximum current concentration of intermediate radical-cations formed in this reaction was measured for the case of 4,4'-dimethoxydiphenylamine.In acetonitrile the radical-cations dimerize, being converted into products from oxidative condensation of the amines, and the corresponding nitrosamines are not observed.The formation of nitrosamines by recombination of the radical-cation with NO is only realized in the presence of proton-accepting solvents and pyridine, in particular.
