523-525Ag(I) catalysed peroxydisulphate oxidation of benzylphenylglycollic and substituted benzylphenylglycollic acids in acetic acid-water mixture (30% v/v) at constant ionic strength is first order each in [peroxydisulphate] and [Ag(I)] and independent of [reductant]. Addition of allyl acetate inhibits the reaction. The thermodynamic parameters have been evaluated. The log k1 values have been fitted With σ+ values and the value of ρ+ calculated. The rate laws have been proposed on the basis of free radical mechanism involving silver(I)
