三酸化硫黄-ピリジン付加化合物によるアントラセンのスルホン化反応

抄録

The sulfonation of anthracene with SO₃-pyridine reported by Battegay was reinvestigated. Contrary with their results that 1-anthracenesulfonic acid was obtained in high selectivity, a mixture of six sulfonic acids was obtained 1- (14%), 2- (4%), 1, 5- (10%), 1, 8-(60%), 2, 6 +2, 7- (12%). The reaction in melting SO₃-pyridine gave 1-anthracenesulfonic acid in the selectivity of 40%.
