  Study of Sulfinate and Sulfenate Complexes Derived from the Oxygenation of Thiolate Sulfur in [1,5-Bis(2-mercapto-2-methylpropyl)-1,5-diazacyclooctanato(2-)]nickel(II)

  摘要：

  A series of nickel(II) complexes containing sulfinate and sulfenate S-donor sites has been prepared from systematic oxygenations of the dithiolate complex [1,5-bis(2-mercapto-2-methylpropyl)-1,5-diazacyclooctanato(2-)]nickel(II) ((bme*-daco)Ni, 1*) and the whole series characterized by mass spectrometry: and X-ray crystallography. The dithiolate complex reacts in organic solvents with molecular oxygen to produce sulfinate (NiS(O)(2)R) complexes, while reactions with hydrogen peroxide have, in addition,permitted the isolation of sulfenate (NiS(O)R) products. The X-ray crystal structures of the complexes [1-(2-mercapto-2-methylpropyl)-5-(2-sulfino-2-methylpropyl)-1,5-diazacyclooctanato(2-)]nickel(II) (2*), [1,5-bis(2-sulfino-2-methylpropyl)-1,5-diazacyclootanato-(2-)]nickel(II)) (3*), [1,5-bis(2-sulfeno-2-methylpropyl)-1,5-diazacyclooctanato(2-)]nickel(II) (5*), and [1-(2-sulfeno-2-methylpropyl)-5-(2-sulfino-2-methylpropyl)-1,5-diazacyclooctanato(2-)]nickel(II) (6*) were determined and metric data compared with previously characterized 1* and 4*, [1-(2-mercapto-2-methylpropyl)-5-(2-sulfeno-2-methylpropyl)-1,5-diazacyclooctanato(2-)]nickel(II). Analysis of the Ni-S-(av) bond distances for homoleptic complexes reveals that the bond distances are in the order Ni-S(O)R (2.167(5)) > Ni-SR (2.159(3)) > Ni-S(O)(2)R (2.127(3)). The average nickel sulfinate S-O distance at 1.459 Angstrom is ca. 0.1 Angstrom shorter than the average nickel sulfenate S-O distance at 1.545 Angstrom. These bond dimensions correlated well with spectroscopic and reactivity data. Electrochemical studies find the Ni-II/I reversible couple to be stabilized by ca. 100 mV with conversion of thiolate-S to sulfenate-S donor, while conversion of a sulfenate to a sulfinate stabilized the Ni-I state by an additional 200 mV. Mass spectrometry delineated O-atom loss pathways to dominate initial fragmentation patterns from the parent ions in the protic matrix thioglycerol; however, SO2 extrusion also occurs and is prominent in a nitrobenzyl alcohol (NBA) matrix. The sulfenate complexes are unexpectedly stable and do not undergo either inter- or intramolecular disproportionation reactions to thiolate and sulfinate, nor do they transfer oxygen to triphenyl- or tributylphosphine. Sulfur dioxide removed oxygen from the sulfenates, yielding thiolates and SO3, whereas no reaction occurred with the sulfinate complexes. Complexes that represent partial oxidation of the sulfurs further reacted with hydrogen peroxide to produce higher oxygenates and also reacted with electrophiles such as alkylhalides to produce S-bound sulfoxide ligands.

  reaction of free ligand with the iron source, Fe(acac)(3), gave good yields in shorter time. With the less sterically encumbered derivative, [(bme-daco)Fe](2), the only successful route to [(bme-daco)Fe](2)O required single O-atom sources such as 4-chloropyridine N-oxide to be present during the preparation of the complex; attempted use of molecular O(2) either during the synthesis or following isolation of

Further characterization by electrochemical and electronic spectral measurements suggests greater electron delocalization in the all-copper complex as compared to the NiCu heterometallic complex. Mass spectral data imply that the mixed-metal Ni(II)(2)Cu(I)(4)S(4) is more stable toward CuCl loss than Cu(II)(2)Cu(I)(4)S(4), a result that is corroborated by extraction

  A series of tetragonally distorted square pyramids of formula N2S2M(NO) (M = Fe, Co) is prepared and characterized by v(NO) IR and EPR spectroscopies, magnetism and electrochemical properties, as well as solid-state crystal structure determinations. While the v(NO) IR frequencies and the ZM-N-O angles indicate differences in the electronic environment of NO consistent with the Enemark-Feltham notation of Fe(NO)}(7) and Co(No)}(8), the reduction potentials, assigned to Fe(NO)(7) + e(-) double left right arrow Fe(NO)}(8) and Co(NO)}(8) + e(-) double left right arrow Co(NO)}(9) respectively, are very similar, and in cases identical, for most members of the series. Coupled with the potential for the M(NO) units to breathe out of and into the N2S2 core plane are unique S-M-N-O torsional arrangements and concomitant pi-bonding interactions which may account for the unusual coherence of reduction potentials within the series.
