General description

Benzyl bromide is an aromatic halide that is mainly used as a protecting agent for protecting hydroxy group of alcohols via O-benzylation reaction.

Application

Benzyl bromide has been used as an initiator in the synthesis of poly(styrene-b-methylmethacrylate) copolymers by atom transfer radical polymerization. It can undergo Menschutkin reaction with 1, 2-dimethylimidazole to form 3-benzyl-1, 2-dimethylimidazolium bromide.

This paper reports the synthesis of (±)-licarin A 1, a dihydrobenzofuran neolignan, resultant of an oxidative coupling reaction of isoeugenol and horseradish peroxidase (HRP) enzyme. Following, three semi-synthetic derivatives from this compound were obtained: benzylated (±)-licarin A 2, methylated (±)-licarin
