Abstract: | Thermal and/or photochemical conversion of a series of copper(II) complexes containing mixed dithiocarbamato–alcohol ligands, CuII(Et2dtc)+ . . . Y− (Y=ClO4−, NO3−), into CuII(Et2dtc)Cl in chloroalkane/alcohol solutions, where chloroalkane=CCl4, CHCl3 or CH2Cl2 and alcohol=MeOH, EtOH or i-BuOH, proceeds in chloroalkanes. Both reactions follow a similar pathway which is more effective the stronger the acceptor properties of chloroalkanes and the weaker the coordinating abilities of alcohols are. A detailed reaction mechanism is proposed which well fits the experimental results obtained by EPR and UV–VIS spectra and quantum yields. |
