The nitrosyl molybdenum complexes ^n- (L = X, n = 2; L2 = phen, n = 0; X = Cl^-, NCS^-, N3), ^n- (m = 0, 1; L = NCS^-, n = 2; L = phen, n = 0) react with EtAlCl2 to form the catalytically active systems for olefin metathesis.The carbene dinitrosyl molybdenum complexes are the real catalysts in these systems.The mechanism by which these complexes are formed was determined from their IR spectra recorded in PhCl in the range 1600-2300 cm^-1 i.e. in the ν(NO), Ν(CN), and ν(NN) regions.The synthesis and characterization of the novel complexes (L = Cl^- and N3) are described.
