Abstract: Nitro group of the nitrated 3-(arylmethylene)phthalide8 was reduced to amino group by 57% hydroiodic acid. When the nitro group was in one of the positions 5, 6, or 7, the double bond between the carbon atoms was reduced, too. However, a dilute (35 — 40%) hydroiodic acid reduced the nitro group only.
