    • f values). Fortunately, under tungsten lamp illumination, the product was found to be colorless, while the diselenide showed an intense yellow spot. Hence, full conversion is judged by the complete disappearance of the yellow spot due to ArSeSeAr. Note that even traces of diselenide present in the mixture show quite intense yellow spots, posing difficulty in judging the conversion. We believe that any one monitoring the reaction by HPLC or 2D-TLC would be able to carry out the decarboxylation under ideal stoichiometry.

    • In the case of halodecarboxylation of cinnamic acids with N-halosuccinimide, we had earlier observed via semiempirical calculation that the halo-equivalent of episelenonium ion intermediate is more stable over the others. See ref 14, and J. P. Das (doctoral dissertation, IIT Kharagpur, Janurary 2005).

    • For electrophilic attack in α,β-unsaturated aromatic systems, a moderately negative p-value within -2 to -4 generally implies a transition state in which the positive charge is not far away from the aromatic ring, and there is partial loss of conjugation.
