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.
在二氯甲烷中用光度计研究黄鎓离子 1a 和 4'-甲氧基黄鎓离子 1b 与各种 π-亲核试剂和三丁基锡烷的反应动力学。亲电性参数 E(1a) = -3.46 和 E(1b) = -4.96 来自等式 log k (20 °C) = s(E + N);这些允许预测黄鎓离子 1a 和 1b 的潜在反应伙伴。
