Abstract

The conventlonal problems of derlvatlve stablllty and fluorescence quantum ylelds In the case of amlnes reacted with o-phthalaldehyde and varlous thlols were clrcumvented by a liquld chromatography/electrochemlstry (LCEC) approach. The degradative hydrolysls of the Ssubstltuted Iso-Indole was Investigated by varylng the sterlc bulk of the thlol used In the o- phthalaldehyde reagent. No appreciable lmprovement In stability accrued until the bulky ...
