Synthesis and characterization of dithioethers, and their RuII and RuIII complexes
摘要:
The syntheses of nine, new dithioethers of the type RS(CH2)(x)SR, where x = 2 or 3 and R is an alkyl chain, as well as the known x = 2, R = phenyl or cyclohexyl compounds, are reported. The known dithioethers react with RuCl3 center dot 3H(2)O to form trans-RuCl2(dithioether) 2 complexes 1 (R = Ph) and 2 (R = C6H11), whereas from the other dithioethers RuCl2[RS(CH2)(x)SR](2)(mu-Cl)(2) complexes have been isolated, where x = 3, and R = Et (complex 3), Pr-n (complex 4), Bu-n (complex 5), and R = (n)pentyl (complex 6). The complexes are well characterized, including X-ray structures for complexes 1-4. The interest in these compounds stems from oxidation of the dithioethers to the corresponding disulfoxides and their Ru complexes.

NbSCl3 was obtained via reaction of NbCl5 with S(SiMe3)2 in anhydrous CH2Cl2, whilst in MeCN solution the same reaction gives [NbSCl3(MeCN)2]. [NbSeCl3(MeCN)2] was obtained similarly from NbCl5 with Se(SiMe3)2. The chalcogenoether complexes, [NbSCl3(ER2)] (E = S: R = Me, nBu; E = Se: R = nBu), were obtained from reaction of NbCl5, ER2 and S(SiMe3)2 in CH2Cl2. The structure of the [Nb2S2Cl6(SMe2)2]

EtOH) solution from which various S-bonded sulfinyl complexes of the type cis or trans-RuIICl2(disulfoxide)2, [RuIICl2(disulfoxide)(H2O)]2(μ-Cl)2, and [Ru2II/IIICl(disulfoxide)]2(μ-Cl)3 were isolated; all three types are well characterized, including X-ray data. One RuIII complex, formulated RuCl3(BPhSE)]2(μ–BPhSE) with the bridging disulfoxide 1,2-bis(phenylsulfinyl)ethane, is also synthesized, but

equiv. of S(SiMe3)2. The isolated complexes were characterised by IR, 1H and 77Se1H} NMR spectroscopy, as appropriate, and elemental analysis. Single crystal X-ray structure analyses for [TaSCl3(MeSCH2CH2SMe)], [TaSCl3(MeSeCH2CH2SeMe)], [TaSCl3(iPrSCH2CH2SiPr)] and [TaSCl3(nBuSCH2CH2CH2SnBu)] have been obtained. The data are compared with the previously described Nb(V) analogues. In contrast to the corresponding
