- Synthesis of Thiol, Selenol, and Tellurol Esters by the Reaction of Organochalcogeno Mercurials with Acid Chlorides
-
Summary: Thiol, selenol, and tellurol esters were prepared by the reaction of bis(organochalcogeno)mercurials with acid chlorides in chloroform or carbon tetrachloride and in the presence of tetrabutylammonium halides as catalysts.

- Syntheses and Vibrational Spectra of Some Tris(alkanethiolato)mercurate(II) Complexes, and Crystal Structure of the Hexakis-(methanethiolato)dimercurate(II) Dianion
-
The complexes (R = Me, cation = Et4N+; R = But, cation = Et4N+, Bu4N+, +) have been prepared.The crystal structure of the methanethiolate complex shows that it contains centrosymmetric dinuclear anions 2- with distorted tetrahedral geometry about the mercury atoms.Vibrational spectroscopic evidence suggests that this complex dissociates on dissolution in ethanol to give mononuclear - species.The ButS- complexes appear to exist as mononuclear t)3>- species both in the solid state and in solution.The metal-sulfur stretching frequencies are assigned for all of the complexes studied, and the vibrational spectra are discussed in terms of the structures of the complex anions involved.Crystal data for 2Hg2(SCH3)6: a 8.656(5), b 9.130(6), c 12.368(8) Angstroem; α 102.16(4), β 105.51(4), γ 105.29(4) deg; space group P, Z 1, R 0.034, Rw 0.042.
