Kinetics of the reactions of flavylium ions with π-nucleophiles

The kinetics of the reactions of the flavylium ion 1a and the 4′-methoxyflavylium ion 1b with various π-nucleophiles and tributylstannane were investigated photometrically in dichloromethane. Electrophilicity parameters E(1a) = -3.46 and E(1b) = -4.96 were derived from the equation log k (20°C) = s(E + N); these allow the prediction of potential reaction partners of the flavylium ions 1a and 1b.
