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.
Phenylselenolate mercury alkyl compounds, PhSeHgMe and PhSeHgEt: Molecular structures, protolytic Hg-C bond cleavage and phenylselenolate exchange

The phenylselenolate mercury alkyl compounds, PhSeHgMe and PhSeHgEt, have been structurally characterized by X-ray diffraction, thereby demonstrating that both compounds are monomeric with approximately linear coordination geometries; the mercury centers do, nevertheless, exhibit secondary Hg...Se intermolecular interactions that serve to increase the coordination number in the solid state. The ethyl derivative, PhSeHgEt, undergoes facile protolytic cleavage of the Hg-C bond to release ethane at room temperature, whereas PhSeHgMe exhibits little reactivity under similar conditions. Interestingly, the cleavage of the Hg-C bond of PhSeHgEt is also more facile than that of the thiolate analog, PhSHgEt, which demonstrates that coordination by selenium promotes protolytic cleavage of the mercury-carbon bond. The phenylselenolate compounds PhSeHgR (R = Me, Et) also undergo degenerate exchange reactions with, for example, PhSHgR and RHgCl. In each case, the alkyl groups preserve coupling to the 199Hg nuclei, thereby indicating that the exchange process involves metathesis of the Hg-SePh/Hg-X groups rather than metathesis of the Hg-R/Hg-R groups.
Synthesis, structure, and reactivity of two-coordinate mercury alkyl compounds with sulfur ligands: Relevance to mercury detoxification
Melnick, Jonathan G.,Yurkerwich, Kevin,Parkin, Gerard

The susceptibility of two-coordinate mercury alkyl compounds of the type X - Hg - R (where X is a monodentate sulfur donor) towards protolytic cleavage has been investigated as part of ongoing efforts to obtain information relevant to understanding the me
Perfluoromethyl element ligands. XLI. [1] compounds of the type (F3C)2EE′R with pseudohalide character (E = P, As; E′ = S, Se, Te)

Perfluoromethyl phosphorus and -arsenic compounds of the type (F3C)2EE′R (E = P, As; E′ = S, Se, Te; R = organic group) are prepared either by dismutation (metathesis) of E2(CF3)4 with (RE′)2/su
Mercury(II) and organomercury(II) complexes of thiols and dithiols, including british anti-lewisite

The dithiols 2,3-dimercapto-1-propanol (British anti-Lewisite) and1,3-dimercapto-2propanol form complexes RHgS～SHgR (R = Me, Ph). The PhHg(II) complexes decompose in benzene and methanol at ambient temperature to form diphenylmercury. A 1:1 complex of Hg(II) with 1,3-dimercapto-2-propanol is dimeric in pyridine. Infrared, Raman, and 1H NMR spectra of RHg(II) and Hg(II) dithiol complexes are compared with those of PhHgSR (R = Me, Et, Pri, But, Ph, CH2CH2OH) and Hg(SR′)2 (R′ = Me, Et,But′, Ph, CH2CH2OH). Phenylmercury(II) thiolates have the coupling constant J(orthoH-199Hg) within the range 144-155 Hz. The complexes PhHgSR and Hg(SR″)2 (R″ = Et, But, Ph) are monomeric in chloroform; the chloroform insoluble complexes Hg(SR?)2 (R? = Me,CH2CH2OH) and organomercury(II) dithiolates are monomeric in pyridine. Aspects of the use of British anti-Lewisite as an antidote for mercury poisoning are discussed.
