5. Cf. a report by B. B. Lampert [Ph. D. thesis, Northwestern University, 1951, p. 167] that treatment of a cold solution of benzo[b]thiophene in carbon tetrachloride with a one-molar quantity of chlorine (plus subsequent shaking with ice-water) gave a 14% yield of 2,3-dichloro-2,3-dihydrobenzo[b]thiophene 1-oxide, identified only by carbon-hydrogen elemental analysis, qualitative tests for chlorine and sulfur, and melting point.
