(GSH) to form MeHgCys and MeHgSG complexes. Herein, it is reported that the N,N‐disubstituted benzimidazole‐based thione 1 containing a N−CH2CH2OH substituent converts MeHgCys and MeHgSG complexes to less toxic water‐soluble HgS nanoparticles (NPs) and releases the corresponding free thiols CysH and GSH from MeHgCys and MeHgSG, respectively, in solution by unusual ligand‐exchange reactions in phosphate

Organomercurials including methylmercury are ubiquitous environmental pollutants and highly toxic to humans. Now it could be shown that N‐methylimidazole based thiones/selones having an N‐CH2CH2OH substituent are remarkably effective in detoxifying various organomercurials to produce less toxic HgE (E=S, Se) nanoparticles. Compounds lacking the N‐CH2CH2OH substituent failed to produce HgE nanoparticles
