Abstract
Photoreduction of [Sb-V(tpp)(OH)(2)](+) (tpp = dianion of 5,10,15,20-t etraphenylporphyrin) yields either the metastable pi-radical anion [Sb -V(tpp(.-))(OH)(2)] or the two-electron reduced [Sb-III(tpp)](+) compl ex; product formation can be channelled in the desired direction by an appropriate choice of the reaction medium and dioxygen regenerates th e starting compound.
