✦ Synopsis


Iminium Carbonic Acid Derivative Salts VII. Part I: Iodides, 2-Methylthio-4,5-dihydrothi~zolium Iodides, and 2-Methylthio-5meth~HhiPeolium Iodides with N-NudeophUes Cyclic salts of the dithiocarbonic acid diester imidium type (3.5) react with NHz-nucleleophiles to the cyclic isothiareas 68. Some of these compounds were oxidized to cyclic isothiourea-SS-dioxides (9,lO). EIedr~philic Reeetic*ls of %M&hylthi~5,6-dihydro-4H-/3-thisziniu Cyclische Salze des Dithidcohlensaure-diuter-imidium Typs (3,5) wurden mit NHz-Nucleophden zu den cyclischen Isothioharnstoffen 6-8 umgesetzt.
