Nitrosylruthenium complexes bearing two 2,2′‐bipyridine (bpy) or 2‐pyridinecarboxylate (pyc) ligands, [Ru(NO)X(bpy)₂]³⁺ (X=CH₃CN, CH₂=CHCN, H₂O, Cl, ONO₂) and [Ru(NO)(OH₂)(pyc)₂]⁺, were used as catalysts for the polymerization of acrylonitrile in N,N‐dimethylformamide (DMF) under air without initiators to obtain polyacrylonitrile (PAN) with a high molecular weight and a narrow molecular weight distribution.
