Crosslinked co-poly/styrene-4-vinyl(N-hcxylpyridinium bromide) was converted with bromine or chlorine to insoluble polymer supported complexes I or 2 respectively, and their reactivity studied in reactions with various aromatic molecules. Reagent 1 was found in all cases to be milder than reagent 2

Diaminopurines, immobilized on a polymeric support are treated with a charge transfer complex of bromine and lutidine to afford 8-brominated derivatives. An ionic complex of bromine and lutidine did not oxidize the purines. 2,6-Dialkylaminopurines could also be oxidized on the a-carbon of their 2-al
