Abstract

5,6-Trimethylenethiapyrylium salts have been obtained for the first time. 5,6-Trimethyleneγ-thiopyrans (or 5,6,7,8-tetrahydro-γ-thiochromenes), which belong to a previously unknown series of two-ring sulfides, are formed by reaction of the 5,6-trimethylenethiapyrylium salts (or 5,6,7,8-tetrahydrothiochromylium salts) with Grignard reagents and lithium aluminum hydride.
