A new multicomponent reaction (multiple-anion-capture reaction) of 1,3dianions with nitriles and oxalic acid-bis(imidoyl)chlorides is reported. This process allows for an efficient and regioselective synthesis of a variety of radialene-shaped pyrroles which constitute structurally new and interestin
