The palladium-catalyzed cross-dehydrogenative-coupling (CDC) reaction of internal alkenes (α-nitro ketene dithioacetals) and terminal alkenes (acrylates) was achieved in AcOH/DMSO using air or AgOAc as the sole oxidant. Styrenes were also applied in the CDC reaction of these internal alkenes with AgOAc as the oxidant. Polyfunctionalized 1,3- and 1,4-dienes were obtained in moderate to excellent yields
钯催化的内烯烃(α-硝基烯酮二
硫缩醛)和末端烯烃(
丙烯酸酯)的交叉脱氢偶联(CDC)反应是在 AcOH/
DMSO 中使用空气或 AgOAc 作为唯一氧化剂实现的。
苯乙烯也用于这些内烯烃与 AgOAc 作为氧化剂的 CDC 反应。在温和条件下以中等至优异的产率获得了多官能化的 1,3- 和 1,4- 二烯,无需对底物进行预官能化。二烯产物很容易转化为相应的胺和衍
