2,9-Dimethyl-3,8-bis(methylsulfanyl)naphtho[2,1-b:3,4-b′]difuran

Abstract

The title compound, C18H16O2S2, was prepared by the Lewis acid-catalysed reaction of 2,3-dihydroxynaphthalene with α-chloro-α-(methylsulfanyl)acetone. The naphtho[2,1-b:3,4-b′]difuran unit is nearly planar, with a mean deviation from the least-squares plane of 0.028 Å. In the crystal structure, aromatic π–π stacking interactions are observed between adjacent molecules.
