Abstract
alpha,beta-Unsaturated hydrazones bearing an ester or a nitrile at C-2 position have been synthesized. They are unreactive towards electron-rich dienophiles but react with electron-poor dienophiles. Dramatic rate enhancements have been observed in concentrated organic solutions of LiNTf(2).
