Federal University, Kaliningrad 236041, Russian Federation 10.3762/bjoc.18.55 Abstract Formation of unusual unsymmetrical dimers or/and indenes via Rh2(esp)2-catalyzeddecomposition of 3-diazo-2-arylidenesuccinimides has been investigated. The reaction proceeded under mild conditions, and its result was
against the A549 human lung adenocarcinoma cell line while N-aryl analogs were non-cytotoxic.
