REACTIONS OF 9-PHENYLTHIOXANTHENE 10-OXIDE WITH ORGANOMETALLIC REAGENTS
It was proved that the reaction between 9-phenylthioxanthene 10-oxide (II) and organometallic reagents proceeds through the formation of 9-phenylthioxanthenyl radical. A new method of synthesis of thiaanthracene derivative was found by the reaction of II with aryllithium.
