Conclusions

  1. 1.

    The polar effects of the substituents in the thiophenol ring have little effect on the position of the exchange equilibria of the metal-proton and metal-metal type involving substituted thiophenols and their C6H5Hg, (C6H5)3Sn, and (C6H5)3Pb derivatives.

  2. 2.

    Depending on the acceptor of the unshared electron pair, in o-substituted thiophenols and their organometallic derivatives the stability of the chelate rings in most cases increases in the order (C6H5)3Sn <(C6H5)3Pb<H<C6H5Hg for five-membered rings, and in the sequence (C6H5)3Sn<(C6H5)3Pb<C6H5Hg<H for six-membered rings.
