“…In the cyclic voltammograms of 14 and 15 , as illustrated in Figure 10 and Table 3, no oxidation waves are observed until +1.20 V, except for an irreversible oxidation at +1.12 V, which is similar to the oxidation of Et 4 NCl (Figure 10). Thus, it may be assigned to the oxidation of free Cl − ions in solution 25. The result implies that 14 and 15 are less easily oxidized than 2 , 12 , 16 , and 17 , mainly owing to the higher valence state of the cations of 14 and 15 and the lower electron density of Os center, which can be inferred from their structures confirmed by single‐crystal X‐ray diffraction.…”

Treatment of [OsCl(2)(PPh(3))(3)] with HC[triple bond]CCH(OH)C[triple bond]CH/PPh(3) produces the osmabenzene [Os{CHC(PPh(3))CHC(PPh(3))CH}Cl(2)(PPh(3))(2)][OH] (2), which is air stable in both solution and solid state. The key intermediate of the one-pot reaction, [OsCl(2){CH=C(PPh(3))CH(OH)C[triple bond]CH}(PPh(3))(2)] (3), and the related complex [Os(NCS)(2){CHC(PPh(3))CH(OH)C[triple bond]CH}(PPh(3))(2)] (7) have been isolated and characterized, further supporting the proposed mechanisms for the reaction. Reactions of 3 with PPh(3), NaI, and NaSCN give osmabenzene 2, iodo-substituted osmabenzene [Os{CHC(PPh(3))CHCICH}I(2)(PPh(3))(2)] (4), and thiocyanato-substituted osmabenzene [Os{CHC(PPh(3))CHC(SCN)CH}(NCS)(2)(PPh(3))(2)] (5) respectively. Similarly, reaction of [OsBr(2)(PPh(3))(3)] with HC[triple bond]CCH(OH)C[triple bond] CH in THF produces [OsBr(2){CH=C(PPh(3))CH(OH)C[triple bond]CH}(PPh(3))(2)] (9), which reacts with PPh(3)/Bu(4)NBr to give osmabenzene [Os{CHC(PPh(3))CHC(PPh(3))CH}Br(2)(PPh(3))(2)]Br (10). Ligand substitution reactions of 2 produce a series of new stable osmabenzenes 11-17. An electrochemical study shows that osmabenzenes 2, 12, and 14-17 have interesting different electrochemical properties due to the different co-ligand. The oxidation potentials of complexes 2, 12, 16, and 17 with Cl, NCS, and N(CN)(2) ligands gradually positively shift in the sequence of Cl

Die reduksie van tris(β-diketonato)mangaan(III) ([Mn(β-diketonato)3]) verbindings na tris(β-diketonato)mangaan(II), asook die oksidasie daarvan tot tris(β-diketonato) mangaan(IV), is ondersoek met behulp van DFT-metodes. Die akkuraatheid van die voorspelling van die reduksiepotensiaal of oksidasiepotensiaal is baie belangrik vir die bepaling van die potensiaalomvang wat geskik is vir die ontwerp van spesifiek vereiste toepassings. Die DFT-funksionele metode M06 het die eksperimentele reduksiepotensiaal tot ‘n hoër vlak van akkuraatheid weergegee, in vergelyking met die M062X en B3LYP metodes. Hierdie studie het ook getoon dat reduksie van verbindings ‘n afname in entropie en ook Gibbs vrye energie, in sowel die gasfase as die oplosmiddelfase, veroorsaak het en gevolglik die hoogste waarde vir totale Gibbs reaksie-energie (ΔGrksie) vir die gereduseerde verbinding getoon het, veral vir dié molekules met sterker elektron-onttrekkende groepe, soos CF3. Dit het gelei tot ‘n reduksiepotensiaalverskuiwing na meer positiewe waardes, vir dié verbindings wat CF3 bevat. Hierdie meer positiewe reduksiepotensiaal van verbindings in die teenwoordigheid van sterker elektrononttrekkende groepe het ook ‘n skuif na meer positiewe oksidasiepotensiaal tot gevolg gehad. Gevolglik kon die oksidasiepotensiaal gaandeweg nie meer binne die eksperimentele venster vir oplosmiddels waargeneem word nie. Die waardes van die molekulêre elektrostatiese oppervlakpotensiaal (MESP) minima en die MESP atoompotensiaal van die Mn atoom en sy gekoördineerde suurstofatome, dien as goeie beskrywers vir die waargeneemde eksperimentele reduksiepotensiaal en kan ook bydra om die eksperimentele reduksie van toekomstige molekules tot ‘n hoë vlak van akkuraatheid te kan voorspel.
