The effect of the organotin compounds R n SnCl 4− n ( n = 1–3; where R = Me, Et, n ‐Bu and Ph) upon oleic (( Z )‐9‐octadecenoic) acid oxidation by dioxygen has been studied at 25, 37, 65, and 95 °C. The promoting effect of organotins upon the formation of oleic acid hydroperoxides is temperature dependent and is at a maximum at a temperature close to the physiological one, but the impact of organotins upon oleic acid peroxidation decreases in the presence of 2,6‐di‐ tert ‐butylphenol. The role of organic free radicals derived from the SnC bond cleavage in the oxidation of oleic acid is discussed. Copyright © 2002 John Wiley & Sons, Ltd.
