The compound (Cr(CO)5As(C6H5)H)2, 1, reacts under thermal Pt-catalysis with dienes in Diels-Alder type reactions to give the cycloadducts 2.Whereas the formation of the acrolein adduct 3 suggests a stepwise reaction, the isolation of diarsene-complexes 4 in the system Pd/C / L (L = donor ligand) suggests a synchronous mechanism.As side products in these reactions, oligocycloarsane-complexes RnAsn(Cr(CO)5)m (n = 4, 5; m = 1, 2), 5, are formed.
