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.

Synthesis of α-Halogeno-Ï-alkylthioalkanes and α,Ï-Bisalkylthioalkanes The reaction of α,Ï-dihalogenated alkanes [X(CH2)nX,,n = 3 - 10]with alkylthiolates affords α-halogeno-Ï-alkylthioalkanes 1 as well as α,Ï-bisalkylthioalkanes 2. Products 1 (40 examples) and 2 (22 examples) are easily isolated in good yields by flash chromatography.

Corrosion inhibition systems, including coated substrates, coating materials and corrosion inhibition compounds, and methods of making the same are disclosed. These systems and methods include corrosion inhibition compounds that are responsive to corrosion at a surface, releasing active inhibitor groups upon a corrosion stimulus. The active inhibitor groups are selected to block corrosion at the surface by inhibiting oxidation reactions, reduction reactions and/or by forming a passivation layer.
