Abstract

Phenacyl and para-substituted phenacyl halides react with ethylenethiourea in acetone at room temperature to yield 2-phenacylmercapto-2-iiidwohium halides (I). Treatment of an aqueous solution of thie salt with ammonium hydroxide yields the Corresponding free baae, 2-phenacylmercapto-Ziidazoline (11). When the para group is hydrogen, bromine, methyl mercapto or phenyl, the infrared spectra of these salts show a carbonyl absorption in the ...
