YieldReaction ConditionsOperation in experiment
74% at 110℃; for 1 h; To a solution of 2,5-dihydroxy-1,4-dibenzoquinone 7 (2.0 g, 1.0 equiv.) in HCl (110 mL) tin granulate (2.068 g, 1.2 equiv.) was added slowly. The reaction was warmed to 110 °C for 1 hour, and when temperature decrease (50-60 °C), was filtered and cooled to 0 °C, to obtain, after crystallization, compound 8 (1.450 g, 74percent) as colorless crystals. 1H NMR (MeOD, 300 MHz) δ 5.0 (br, 4H), 5.90 (s, 2H).

1,2,4,5-Tetrahydroxybenzene STR76
2,5-Dihydroxy-1,4-benzoquinone (4.00 g, 28.55 mmol) was suspended in water (50 ml, distilled) followed by Na2 S2 O4 (10.00 g, 57.47 mmol) and HCl (5.5 g, 55.75 mmol conc. soln.).
The mixture was stirred 30 min. at room temperature and evaporated to dryness.
The residue was washed with THF (40 ml) and filtered.
The THF was evaporated yielding 2.00 g (14.07 mmol, 49.3percent) of the title substance.
