An efficient and simple synthesis of various functionalized halonaphthalenyl ethers
and esters in moderate to good yield was achieved via rhodium(II)-catalyzed reaction
of readily available diazo compounds with benzyl halides or acid halides. This methodology
has several advantages, such as ease of handling, mild reaction conditions, bromine-
or chlorine-free route, and the use of an effective catalyst. The synthesized compounds
were further converted into valuable polyaromatic compounds using the Suzuki reaction.
