Summary

5-Methoxythionaphthene (II) and the hitherto unknown 6-methoxy-(IV), 7-methoxy- (VI) and 5-ethoxy-thionaphthenes (VIII) have been prepared by the new synthesis. 6-Methoxy-5-methylthionaphthene (X) was also prepared similarly and gave 6-methoxy-5-methylthionaphthene-1-dioxide (XI) on oxidation. Demethylation of (VI) and (X) gave 7-hydroxythionaphthene (XIII) and 6-hydroxy-5-methylthionaphthene (XIV).
