The slight interest in monothioformals has been centered upon compounds containing a five- membered ring-readily prepared from a carbonyl coinpound and mercaptoethanol. Other examples of this type of compound can be prepared by the method of Bohme3 but only with difficulty and in low yields. There has been no report of a compound containing the monothioformal system in a six-membered ring. We set about filling this gap by ...
