Polyvinylpyrrolidone-bromine complex: An efficient polymeric reagent for selective preparation of benzyl bromides in the presence of hexamethyldisilane
Benzylic bromides were conveniently obtained in high yields via the reaction of the corresponding alcohols with crosslinked polyvinylpyrrolidone-bromine complex (PVPP-Br<sub>2</sub>)/hexamethyldisilane in chloroform at reflux condition. Selective conversion of benzyl alcohol to benzyl br...
