Photochemical chlorodecarboxylation via an electron transfer mechanism
Abstract
A new method of chlorodecarboxylation of carboxylic acids via N-acyloxyphthalimides is developed; the reaction proceeds upon irradiation of N-acyloxyphthalimides in the presence of 1,4-diazabicyclo[2.2.2]octane in ButOH–CCl4–H2O (53:42:5 v/v) in moderate to high yields.
