Abstract

Heterocyclic chalcogenones were prepd. by reaction of S, Se, or Te with ionic liqs. or salts [I; Ra = (substituted) alkyl, cycloalkyl, aryl, aralkyl, alkylaryl; Q = (unsatd.) (substituted) linker to form a ring of 5-10 members; X- = anion selected from conjugate bases of HX having a pKa value of >2.5]. Thus, 1-butyl-3-methylimidazolium acetate was heated with stoichiometric S at 75° for 48 h to give 1-butyl-3-methylimidazole-2-thione. [on SciFinder(R)]
