Abstract Treatment of Ru(NO)Cl3·xH2O with 1 equiv. bidentate Schiff bases in the presence of triethylamine in DMF/THF afforded a series of anionic ruthenium(II) nitrosyl complexes of the type [Et3NH][Ru(κ2-N,O-LR)(NO)Cl3] (HLR = 2-butyliminomethyl-phenol 1, 2-(benzylimino-methyl)-phenol 2, 2-[(4-chloro-phenylimino)-methyl]-phenol 3, 2-[(4-nitro-phenylimino)-methyl]-phenol 4, 2-[(2,6-diisopropyl-ph

ligands with phenolic, imine and various side chain donors yields complexes of type [MOCl3(ligand)2] in which the ligand generally binds as a neutral monodentate imine donor. Electron spin resonance spectra suggest that these complexes have a cis-mer structure. These complexes are not converted to the bidentate anionic ligand complexes [MoOCl(L)2] by refluxing in alcohols, but the latter may be prepared
cylideneiminato]oxovanadium(IV) is monomeric in the solid state. The co-ordination polyhedron, which in the crystal has C2 symmetry, is based on a distorted trigonal bipyramid. The three oxygen and vanadium atoms are in the equatorial plane and the two nitrogen donors occupy axial positions. The vanadium–oxygen bond length (1.615 Å) is among the largest found in oxovanadium complexes.

Synthesis of Mesoionic Isoquinolines by Rhodium(III)-Catalyzed C−H Activation
Hydroxyl‐substituted benzaldimines underwent a RhIII‐catalyzed C−Hactivation and annulation with alkynes to provide novel mesoionicisoquinoline derivatives in moderate to excellent yields using oxygen as an internal anion source. This simple and efficient approach has a broad substrate scope.

The reactions of the chloromanganese(III) complexes of the Schiff bases derived from salicylaldehydes or β-diketones and diamines or monoamines with superoxide ion, O2−, in dimethyl sulfoxide were investigated. The complexes were found to react to give either the oxygenated Mn Schiffbasecomplexes or the reduced Mn(II) Schiffbasecomplexes. The difference in the reactivity toward O2− was correlated
