A series of chromium(II) complexes containing the tripodal ligands tmpa, Me 2 uns‐penp, Me 4 apme and Me 6 tren were prepared and investigated with regard to their reactivity towards dioxygen. It was possible to structurally characterize the complexes [Cr(Me 2 uns‐penp)Cl] 2 (BPh 4 ) 2 , [Cr(Me 6 tren)Cl]Cl, [Cr(Me 4 apme)Cl]BPh 4 and [Cr(Me 4 ampe)Cl 3 ]. The complexes show reactions with dioxygen, but it was not possible to characterize intermediates of these reactions. The oxidation behavior of the complexes towards organic substrates like toluene was investigated and oxidation of toluene to benzaldehyde was observed.
