Abstract: 

Copper complexes with bis(piperidinyl)methane (BP) and bis(quinolinyl)methane (BQ) ligands were investigated. A dinuclear carbonato‐bridged copper(II) complex as well as a dinuclear copper(I) complex with BP ligands were structurally characterized. The reaction of a copper(I)–BP complex was investigated by low‐temperature stopped‐flow techniques, which showed that the very fast formation of a bis(µ‐oxido)copper intermediate leads to an intramolecular ligand hydroxylation. However, substrates such as benzyl alcohol could also be oxidized with this complex. In contrast, no intermediates could be observed spectroscopically for complexes with the BQ ligand or derivatives of this ligand. Instead, complex reaction behavior was observed when copper(II) chloride was treated with BQ in air or under inert conditions. Several crystal structures helped to establish mechanisms for these reactions. A coordination polymer was obtained as an interesting reaction product.
