| Abstract: | Summary The reaction of dichlorotetrakis(pyridine)cobalt(III) chloride. CoCl2(Py)4]Cl, with alkyl- or arylamines in EtOH or i-PrOH yielded CoCl2(Py)2] in all cases. This reduction of CoIII to CoII takes place only in the presence of the amines. CoCl2(Py)2] in EtOH is oxidized by Cl2 gas and in the presence of pyridine gives CoCl2(Py)4] +, while in pyridine alone CoCl2(Py)4] is formed. |
