Peroxides and Related Compounds

Peroxides and Related Compounds.— Triphenylphosphine has been shown to react with the dioxetan (61) to give the quinquecovalent compound (62). This decomposes to give an epoxide on heating. Several peroxides and polyperoxides react with alkyl- and aryl-phosphines in the presence of water. Alcohols are 

The substituted biphenyl (68) readily forms a carbazole (69), whereas (70) reacts to give a phosphineimine,

Recently, Maruta et al. [112] have found that methanol extracts of roots of burdock show a significant antioxidant activity in an in vitro lipid peroxidation assay, and have isolated five caffeoylquinic acid derivatives (CQAs) from the roots of burdock (Arctium lappa L ), an edible plant in Japan. Antioxidant activities of DCQAs and related compounds have been investigated by measuring the hydroperoxidation of methyl linolate via radical chain reaction. This study indicates that in this particular system caffeic acid and CQAs are more effective than a-tocopherol. These results approximately agree with our findings [38], Additionally, CQAs as the principle antioxidative substance in burdock root have been characterized.
