Abstract: A detailed investigation on the effect of solvent polarity, temperature, and microwave irradiation on periselectivity in cycloaddition reactions of pentafulvenes with 3-oxidopyrylium betaine is described. The base catalyzed generation of 3-oxidopyrylium betaine in CHCl3 resulted in the exclusive formation of [6þ3] adducts. With increase in solvent polarity and temperature, mixtures of [6þ3] and [3þ2] adducts were formed, where as under microwave irradiation, [3þ2] adducts were formed exclusively. The experimental results have been rationalized on the basis of theoretical calculations.
