TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The hydrogen chalcogenide is prepared by protonation of organo-anion and followed by decarboxylation to alcohol. The organosilyl chalcogenide is prepared by desilylation of bis(organosilyl)chalcogenide and followed by decarboxylation of the intermediately formed O-silylorganocarbonate anion to organosilylether. The ionic liquid with chalcogenide anion is prepared by reacting cation precursor for ionic liquids as starting material with dimethyl carbonate and subsequently in situ with the chalcogenide compound. Preferred Components: The chalcogenide compound is a chalcogenide hydrogen, bis(organosilyl)chalcogenide, organosilyl hydrogen chalcogenide, polychalcogenide and/or N-H-functional ammonium chalcogenide. The chalcogenide anion is organosilyl chalkogenide, hydrogen chalkogenide and/or poly chalcogenide, preferably divalent negatively charged chalcogenide. The method employs sulfur, selenium and/or tellurium as a chalcogen component. The organo-anion is a linear or branched acyclic or cyclic alkyl group as organo group bonded to the carbonate anion. The organic group includes linear or branched acyclic or cyclic alkyl group having a 1-20C and/or hydrogen in the bis(organosilyl)chalcogenide or organosilyl chalkogenide. The cation has substituted structures with ionic nitrogen, carbon, phosphorus and/or sulfur, preferably substituted imidazolium compounds of formula (I), substituted pyridinium compounds of formula (II), substituted ammonium compounds of formula (III), substituted phosphonium compounds of formula (IV), substituted sulfonium compounds of formula (V), substituted guanidinium compounds of formula (VI), substituted piperidinium compounds of formula (VII), substituted pyrrolidinium compounds of formula (VIII) or substituted sulfoxoium compounds of formula (IX).R4-R47 = H or 1-20C linear or branched acyclic or cyclic alkyl. EXAMPLE - 26.9 g 30% Solution of 1-ethyl-3-methyl-imidazolium methyl carbonate in 43.4 mmol methanol was dissolved in hydrogen sulfide to obtain a solution. Then the solution was concentrated under high vacuum, the residue was dried under vacuum, and recrystallized from acetonitrile-diethyl ether mixture at -30 degrees C to obtain 4.62 g 1-ethyl-3-methyl-imidazolium-hydrogen sulfide with 74% yield.
