Descripción
Sumario:	Several stilbenes and styrenes have been treated with heteropolyacid] (HPA) supported over silice. The compounds obtained were characterized by <SUP>1</SUP>H and <SUP>13</SUP>C-NMR and the yields were compared with those obtained using H<SUB>2</SUB>SO<SUB>4</SUB> (c) and ethyl poliphosphate (PPE).
