Abstract

ABSTRACT The photodecarboxylation of suprofen in the carboxylate form was studied in aqueous medium as a function of the temperature, the concentration and the presence of oxygen by steady-state and time-resolved photochemical techniques. The process is characterized by an activation energy of 9–10 kcal/mol, the precursor state being the lowest triplet which is of π, π* nature. The reactivity of the drug was also studied in the β- ...
