on reaction of naphthazarin (5,8-dihydroxy-1,4-naphthoquinone) with the oxidising radicals OH˙, O˙–, N˙3, Br˙–2, SO˙–4, ĊH2CHO and ĊHCHO– have been determined by pulseradiolysis. Although all these oxidants give some semioxidised naphthazarin, other species such as adducts may also be formed. SO˙–4, O˙– and N˙3 in strong alkali appear to lead predominantly to semioxidised naphthazarin which exists in
