The cycloaddition reactions of some aryl conjugated p-benzoquinones with nitrilimines were studied.Depending upon the reaction conditions mono- and/or bis- adducts were isolated only from carbon-carbon double bond.The structure determination was unequivocally established by an X-ray analysis carried out on a bis-adduct.The observed regio-, as well as site-selectivity was qualitatively correlated with frontier molecular orbitals of the reacting species.
