Microphotochemistry: 4,4′-dimethoxybenzophenone mediated photodecarboxylation reactions involving phthalimides

Abstract

A series of 4,4'-dimethoxybenzophenone mediated intra- and intermolecular photodecarboxylation reactions involving phthalimides have been examined under microflow conditions. Conversion rates, isolated yields and chemoselectivities were compared to analogous reactions in a batch photoreactor. In all cases investigated, the microreactions gave superior results thus proving the superiority of microphotochemistry over conventional technologies. © 2011 Shvydkiv et al.
