Echegoyen. , University of Texas at El Paso, DMR 1205302. The isolation of highly reactive molecules, featuring unique chemical properties, can pose a real challenge. One strategy for the stabilization of reactive molecules is to wrap them within super bulky molecular platforms or supports.. 16-3. Groups that donate electrons by resonance activate and direct ortho and para.. The groups –NH. 2. and –OH strongly activate the benzene ring..
