Autoxidation von CuI-Komplexen, II: Mechanismus der Autoxidation von Komplexen mit einzähnigen Stickstoffliganden

Abstract

The autoxidation of cuprous complexes with monodentate nitrogeneous bases (L) has been studied spectrophotometric-ally and by following the O₂-consumption with an oxygen sensor. The proposed mechanism includes two different oxygenated species. CuL₂O₂⁺ is less reactive than CuL₃O₂⁺ by many powers of magnitude which is explained by the fact that  CuL₂O₂⁺ has a coordination number of 3, specific for Cu^I, whereas CuL₃O₂⁺ may gain quasiplanar, Cu^II specific, symmetry by molecular vibration.
