Abstract
UV irradiation of hitherto unknown 4,5-bis-benzo[b]thiophen-3-yl-[1,3]dithiol-2-one gave 3-(3-benzo[b]thienyl)-thieno[3,4-c]benzo[e][1,2]dithiine by loss of carbon monoxide and rearrangement, whereas 4,5-bis-(2-bromo-phenyl)-[1,3]dithiol-2-one gave a polymeric material containing S-S bridges. The structures of both photoproducts were demonstrated on the basis of chemical behaviour and/or X-ray diffraction. © 2009 Elsevier Ltd. All rights reserved.
