Abstract
The antioxidant activity of hydroxychromanones and hydroxychromanes with a thiopropionate group in the oxidation of tetralin was evaluated at 61 and 1 40 degreesC. Both phenols were found to be intrinsically much more active a t high temperature than the corresponding forms without a thiopropionate gr oup. This high activity is attributed to an additional antioxidant function resulting from the introduction of a thiopropionate group into the aromati c ring. (C) 2001 Elsevier Science Ltd.
