Reactions of VCl3 with chiral derivatives of dihydrophenanthroline (2R,4R,9R,11R)-3,3,10,10-tetramethyl-1,2,3,4,6,7,9,10,11,12-decahydro-2,4:9,11-dimethanodibenzo[b,j][1,10]phenanthroline (L1) and diazafluorene (1R,3R,8R,10R)-2,2,9,9-tetramethy1-2,3,4,7,8,9,10,12-octahydro-1H-1,3:8,10-dimethanocyclopenta [1,2-b:5,4-b']diquinoline (L2) in acetonitrile in air yield mixtures of [V-III(L142)(CH3CN)Cl-3] and [(VO)-O-IV (L1/L2)(CH3CN)Cl-2] (I, II) which were characterized by elemental analysis, IR spectroscopy and magnetic susceptibility data. The behavior of these mixtures in different solvents was investigated by V-51 NMR and EPR spectroscopies as well as optical rotation. Recrystallization of a [V-III(L1)(CH3CN)Cl-3]/[(VO)-O-IV(L1) (CH3CN)Cl-2] mixture from CH2Cl2/Et2O affords a V(IV) complex, [(VO)-O-IV(L1)(H2O)Cl-2]center dot nCH(2)Cl(2) (III). Recrystallization from MeOH/Et2O leads to complete oxidation to V(V) complex [(VO)-O-V(L1)(OMe)Cl-2] (IV), which was characterized by X-ray crystallography, IR, V-51 and H-1 NMR spectroscopies.
