Abstract
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 Co-III to Co-II takes place o nly in the presence of the amines. [CoCl2(Py)(2)] in EtOH is oxidized by Cl-2 gas and in the presence of pyridine gives [CoCl2(Py)(4)](+), w hile in pyridine alone [CoCl2(Py)(4)] is formed.
