The triplet state of benzophenone oxidizes Ni((14)aneN/sub 4//sup 2 +/ to a Ni(III) intermediate which subsequently produces the dimer of the complex as a product. The nature of the product was confirmed by structural studies. (Ni(13-At))/sup +/ reacts with the triplet of fluorenone and /sup 2/Estate of Cr(bpy)/sub 3//sup 3 +/ forming also a dimer in a reaction that involves different intermediates. Intermediates in the photoinduced oxidations of the macrocycles have been investigated by flash photolysis. The mechanism of the photoinduced oxidation is discussed in terms of the reported properties of the macrocycles.
