The oscillatory behaviour of two new substrates namely, 2-thenoyltrifluoroacetone and cyanoacetic acid in the Briggs Rauscher (B-R) system was studied in detail employing a mixed medium: aqueous acetonitrile. The effect of acetonitrile concentration on the oscillatory behaviour is investigated. It is found that employing the aqueous organic mixed media is highly beneficial in the oscillatory study, enabling the study of water-insoluble substances.
