  Manganese(IV) complexes Mn(R-R′-sap)2, where H2(R-R′-sap) denotes 2-(salicylideneamino)phenols with the substituent R on the salicylaldehyde ring and the R′ on the o-aminophenol ring, were prepared by the oxidation of binuclear manganese(II) complexes Mn2(R-R′-sap)2 with tetrachloro-o-benzoquinone (TCOQ). The complexes showed magnetic moments corresponding to three unpaired electrons and strong absorptions

  In methanol, the reaction of Ti((OPr)-Pr-i)(4), N-(2-hydroxyphenyl)salicylideneimine (H(2)Sap) and 8-hydroxyquinoline (HQ) in stoichiometric ratio 1:1:x yielded Ti(Sap)(2) precipitate as initial product even when x was as high as 10. However, when the reaction mixture with x = 2 was left standing for 12 h or more, a small amount of red crystalline Ti(Sap)Q(OMe) was isolated. Addition of wet acetonitrile to the reaction mixture with x = 10, small amount of another red crystalline [Ti(Sap)Q](2)(mu-O) was obtained after standing for 2 days. The reaction between TiQ(2)((OPr)-Pr-i)(2) and H(2)Sap in methanol with stoichiometric ratio of y: 1 also yielded Ti(Sap)(2) as initial product even for y as large as 10. H-1 NMR investigation of the reaction of TiQ(2)(OMe)(2) with H(2)Sap revealed that Ti(Sap)Q(OMe) was not detected initially. These experimental results can be explained based on a mechanism that includes: (i) rapid reaction of H(2)Sap with Ti(IV) centers to form Ti(Sap)(2); (ii) equilibrium between TiQ(2)(OMe)(2) and Ti(Sap)Q(OMe); (iii) equilibrium between Ti(Sap)Q(OR) and Ti(Sap)(2); and (iv) limited solubilities of Ti(Sap)Q(OR) and Ti(Sap)(2). The equilibrium constants and solubilities in the mechanism were determined by the H-1 NMR spectral method. The structures of Ti(Sap)Q(OMe) and [Ti(Sap)Q](2)(mu-O), consisting octahedrally coordinated Ti(IV), were determined by X-ray diffraction method. (C) 2006 Elsevier Ltd. All rights reserved.
