実験手順

A suspension of 2,3-bis(4-methoxyphenyl)thiophene (6.6 g, 22.3 mmoles) and 2,4-dinitrobenzenesulfenyl chloride (5.5 g, 22.3 mmoles) in 55 ml of trifluoroacetic acid was heated at reflux for 15 minutes. The reaction mixture was cooled in ice; the lustrous crystals were collected and washed with cold ether to give the title compound (9.4 g), m.p. 143°-145°
