LUCIAN GABRIEL BAHRIN, HENNING HOPF, PETER GEORGE JONES, KAMEL EARAR, LUCIAN MIHAIL BIRSA SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF A NEW IODINE-CONTAINING PHENACYL N,N-DIETHYLAMINO CARBODITHIOATE
The synthesis of 1-(2-hydroxy-5-iodophenyl)-1-oxaethan-2-yl-N,N-diethylamino-1-carbodithioate was achieved from w-bromo-2-hydroxy-5-iodoacetophenone and sodium N,N-diethyldithiocarbamate, and the structure of the new phenacyl carbodithioate was confirmed by X-ray analysis. Upon acid-catalyzed cyclization of dithiocarbamate 3, the corresponding 1,3-dithiolium perchlorate 4 was obtained. Conversion of the latter into mesoionic derivative 5 was achieved in a basic environment. All new compounds were characterized using NMR spectroscopy.
