Reaktionsschritte
3,4,5-Triacetoxybenzoic acid (296.23 g, 1 mol) was slurried in a 2 L flask in CH2Cl2 (1.0 L), and oxalyl chloride (113 mL, 1.3 mol) as added, followed by slow, dropwise addition of N,N-dimethylformamide (1.5 mL). After 2 hours at RT, gas evolution had ceased, and 3,4,5-triacetoxybenzoyl chloride was isolated by evaporation under reduced pressure.
