The power of carboxylates: Simple carboxylate salts can rival strong amidine bases, such as DBU, in their catalytic power to isomerize β,γ-unsaturated thioesters to corresponding conjugated α,β-unsaturated thioesters. The mechanism involves a rate-determining protonation step!
羧酸盐的能力:简单的羧酸盐将 β,γ-不饱和硫酯异构化为相应的共轭 α,β-不饱和硫酯的催化能力可与强脒碱(例如 DBU)相媲美。该机制涉及决定速率的质子化步骤!
