Cs. Rajesh et al., PHOTOELECTRON TRANSFER INDUCED DECARBOXYLATION OF SUBSTITUTED CARBOXYLIC-ACIDS ACROSS A LIQUID LIQUID INTERFACE/, Tetrahedron, 53(49), 1997, pp. 16817-16834
Methylene blue photocatalyzed electron transfer reactions of some phen
oxyacetic acid derivatives and N-phenylglycine across a liquid/liquid
interface led to their efficient decarboxylation. Nanosecond laser fla
sh photolysis studies of this process. in a reverse micellar system of
Aerosol-OT (AOT)-benzene-water indicated that the liquid/liquid inter
face acts as a barrier in controlling the energy wasting back electron
transfer. Intramolecular C-C bond forming reactions of these radicals
were utilized for the synthesis of various chroman derivatives. (C) 1
