Applications

1,2-Dibromobenzene is used as a precursor in the preparation of 3-(2-bromophenylthio)-4H-[1]benzopyran-4-one using copper as a reagent. It is involved in the preparation of isoindoloquinazolinones by the carbonylation reaction with 2-aminobenzyl amine using palladium as the catalyst.

Notes

Incompatible with strong oxidizing agents.
