Article abstract of DOI:10.1021/jo01297a004

Silica gel has been converted to silylated derivatives which can be converted to sensitizers for singlet oxygen formationn.The silica gel sensitizers, Si>-rose bengals, are versatile and useful in both polar and nonpolar media. Si>-Rose bengal has been studied as a source of singlet oxygen and its uses in reactions of sulfite ion, tryptophan, and 2,3-diphenyldioxene are reported.Results are compared with unbound and polystyrene-based rose bengal (

-rose bengal).
