Description and Uses
1,2,4-tribromobenzene is used in the synthesis of hyper branched poly(p-phenylene ethynylenes). It is 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. It is a compound commonly used in organic synthesis reactions.
