DABCO catalyzed the cross-Rauhut-Currier/transesterification reaction of α-cyano-α,β-unsaturated ketones and aryl acrylates was discovered. The reaction rate law was determined by an integral method under pseudo-first-order reaction conditions, which assisted in proposing the mechanism of cross-Rauhut-Currier reaction promoted by Brønsted acid and establishing the rate-determining step.
DABCO 催化了 α-氰基-α,β-不饱和酮和芳基丙烯酸盐的交叉 Rauhut-Currier/酯交换反应。在准一级反应条件下,通过积分法确定了反应速率定律,这有助于提出 Brønsted 酸促进的交叉 Rauhut-Currier 反应的机理,并确定了速率决定步骤。
