A series of 2,11-dithia[3]metacyclo[3](1,3)pyrenophanes are obtained by the coupling reaction of the corresponding 1,3-bis(bromomethyl)pyrene and bis(sulfanylmethyl)benzenes in ethanol under the high dilution conditions. The conformational studies of dithia[3]metacyclo[3](1,3)pyrenophanes as well as the ring current interactions derived from pyrene ring are described.
The use of coal fly ash as a new support for a reagent for organic synthesis was investigated. Coal fly ash supported sodium sulfide was found to be an effective reagent for the synthesis of dithiacyclophanes, notably giving better results than alumina-supported sodium sulfide.
