Chemistry of the Condensed Tannin B-ring
1989The chemistry of the condensed tannin B-ring is closely related to that of the parent phenols — phenol, catechol, and pyrogallol. Many of the same reactions observed for the simple phenols can be reproduced on the tannin B-ring. These include esterification, etherification, and electrophilic addition for all the types, and metal chelation, oxidation ...
