The Cover Feature shows a facile synthesis of 1,4‐enediones (found in several bioactive molecules) under microwave irradiation by reacting easily available arylmethylketones with DMSO or diphenyl sulfoxide in presence of TBAI and persulfate. In addition, the E‐isomer was converted to the Z‐isomer using eosin Y as photocatalyst. We took the picture of sunset near the mighty river Brahmaputra which is considered the lifeline of the state Assam, India. The figure shows different products obtained by using two different sulfoxides and conversion of E ‐ to Z ‐isomer in presence of light. More information can be found in the Communication by M. L.
