Abstract
The acylcobalt salophens (III), prepared from (I) and the acyl chlorides (II), react with diphenyl disulfide and diselenide (IV) under irradiation to give the thiolo and seleno esters (V).
ChemInform Abstract
The acylcobalt salophens (III), prepared from (I) and the acyl chlorides (II), react with diphenyl disulfide and diselenide (IV) under irradiation to give the thiolo and seleno esters (V). Photolysis of (III) with activated olefins such as (VI), (VIII), or (X) gives the coupling products (VII), (IX), (XI), and (XII). The derivatives (IIId) and (IIIe) undergo ring closure upon irradiation, forming the cyclopentanones (XIII) - (XV).
