Abstract
Chloromethylated crosslinked co-polyvinylbenzene-divinylbenzene (2% DVB) wa s treated with triphenylphosphine and then with sodium bromate and hydrobro mic acid to afford red colored insoluble polyvinylbenzyltriphenylphosphoniu m supported tribromide. This reagent could be used as a mild and efficient monobrominating reagent for activated aromatic compounds such as phenols, a romatic ethers, aromatic amines and acetylanilines with good yields and hig h pma-selectivity.
