- NONCONVENTIONAL FRIEDEL-CRAFTS CHEMISTRY III. ON THE REGIOSPECIFIC SYNTHESIS OF SPIRO-4'-ONE DERIVATIVES
-
The rection of 1-oxa-4-thiaspirononan-2-one (4) and/or 1-oxa-4-thiaspirodecan-2-one (5) with arenes (6) under the catalytic action of aluminum chloride afforded in all cases spiro-4'-ones (7a - g and 8a - g), -acetic acid, (9a - g and 10a - g), cycloalkylthioacetic acids, (11 and 20) aryl cycloalkyl sulfides, (14 and 23) diarylsulfides (15), diaryl disulfides and dicycloalkyl disulfides (13 and 22).The mechanisms of these reactions are discussed.Key words: Spiroisothiochroman-4-ones; Friedel-Crafts reactions.
