Of coordinated thiolate

Table 88 Rate Data (at 25 °C) for Oxidation of Coordinated Thiolate by H202 (see text)...

Equation (80) represents the transformation of coordinated thiolate in the dark green triscysteinate complex of cobalt(III) by oxidation using hydrogen peroxide to the yellow sulfinate. In full, it can be written... 

The rates of Sul methylation of coordinated thiolates, selenates and sulfenates (e.g., [Cr(en)2(SCH2CH2NH2)] ) by Mel have been... 

The significance of this discovery is that control of the degree of polymerization and of coordination modes of the thiolate precursors is hkely to affect the shape of the final nanoproduct in a solventless method. Since traditional thiol-metal coordination chemistry is well established, this affords a great opportunity to join the traditional coordination chemistry with an increased variety of nano-... 

Estimated from Eq. (3) and parameters in Tables I and II. c These ions are reduced by thiols. Since Cu(II) forms less stable complexes with thiols than Cu(II), this will always occur in an environment of thiols alone. However, log Ki for Fe(III) with thiols is larger than for Fe(II), and so log p4 for Fe(III) with ME should be proportionately much larger them with Fe(II). Thus, coordination of four thiolate groups, as occurs in electron transfer proteins, will lead to a very stable Fe(III) complex, which is much less easily reduced to Fe(II) than when only a single thiolate is coordinated. 

An S4 coordination sphere of the type seen in the Ada protein, where four cysteines coordinate, was achieved with the tridentate tris(2-mercapto-l-phenylimidazolyl)hydroborato ligand. The zinc thiophenolate derivative showed reactivity of the thiolate linkage (Figure 8).506...
