Selective benzylic bromination of 2-methylnaphthalene
A practical synthesis of 2-(bromomethyl)naphthalene (1) by selective benzylic bromination of 2-methylnaphthalene (2) with bromine in heptane in the presence of lanthanum acetate hydrate is described.

The easy preparation of many benzylic bromides using molecular bromine as a halogenating in the presence of catalytic amounts of lanthanum tri-acetate
Many benzylic brominations were easily achieved by molecular bromine in CCl4 in presence of 1 percent of La (OAc)3 and a standard room lighting lamp.The selectivity is excellent except for certain electron-rich systems (p-methylaniline, p-cresol).
