Study on quantitative analyses of hydroperoxides and alcohols by NMR shift reagent

Abstract Recently, much literature concerning the effects of NMR shift reagents upon compounds with Lewis's basic functional groups have been reported. These literatures have shown the effects of NMR shift reagents upon hydroxyl, amino, carbonyl, ether, ester carbonyl, cyano, and epoxy compounds but not hydroperoxyl compounds. Chemical and paramagnetic shifts of protons in t‐butyl and cumene hydroperoxides, t‐butyl and 2‐phenyl‐2‐propyl alcohols, and autoxidized methyl linoleate with incremental additions of an NMR shift reagent were determined. These experimental results indicated that each alcohol and hydroperoxide could be determined separately and quantitatively even in their mixtures. Moreover, this method can be recommended to obtain information about the structures of hydroperoxides, as well as alcohols.
