DPPH (= 2,2-Diphenyl-1-picrylhydrazyl) Radical-Scavenging Reaction of Protocatechuic Acid (= 3,4-Dihydroxybenzoic Acid): Difference in Reactivity between Acids and Their Esters

Protocatechuic acid (= 3,4‐dihydroxybenzoic acid; 1) exhibits a significantly slow DPPH (= 2,2‐diphenyl‐1‐picrylhydrazyl) radical‐scavenging reaction compared to its esters in alcoholic solvents. The present study is aimed at the elucidation of the difference between the radical‐scavenging mechanism...
