General description
1,2,4-tribromobenzene on photochemical dehalogenation in open-air solutions of acetonitrile yields 1,4-dibromobenzene, 1,3-dibromobenzene and 1,2-dibromobenzene.
Application
1,2,4-tribromobenzene was used in the synthesis of hyperbranched poly(p-phenylene ethynylenes). It was used as cross-linking reagent during Pd-catalyzed cross-coupling of 2,5-diiodo-4-[(2-ethylhexyl)oxy]methoxybenzene and 1,4-diethynyl-2,5-bis-(octyloxy)benzene.

The photochemical dehalogenation of 1,2,4-tribromobenzene, 1,2,3,5-tetrabromobenzene and pentachlorobenzene in open-air solutions of acetonitrile using natural and artificial sunlight as the irradiation source has been investigated. The regiochemistry of mono-dehalogenation has been determined for 1,2,4-tribromobenzene and 1,2,3,5-tetrabromobenzene. Pentachlorobenzene did not react.
