Description

General description

4-Chlorobenzyl bromide undergoes carbonylation in the presence of dimer of chloro(1,5-cyclooctadiene)rhodium(I) to yield the corresponding phenylacetic acid. It can be synthesized by reacting 4-chlorobenzyl alcohol with bromodimethylsulfonium bromide (BDMS) It can also be synthesized by refluxing a mixture of 4-chlorobenzaldehyde, chlorotrimethylsilane, 1,1,3,3-tetramethyldisiloxane and lithium bromide.

Application

4-Chlorobenzyl bromide may be used to synthesize 1-(4-chlorobenzyl)-2-(pyrrolidin-1-yl-methyl)-1H-benzimidazole dihydrochloride
