Popis:	The diacetylation of phenoxathiin under the typical conditions for Friedel-Crafts reaction results in a mixture consisting of 2,7-diacetylphcnoxathiin (3) and 2,8-diacetylphenoxathiin (9). The compound hitherto descrihed in the literature as 9 proved to be in reality the mixture. For the first time, the compound 3 was isolated, purified and had its structure established. 3,4′-Diethyldiphenyloxide as well as 2,7- and 2,8-diethylphenoxathiins and their sulphones and sul-phoxides have been synthesized.
