A new protocol for the synthesis of N-vinyl azoles using vinyl selenones and azoles in the presence of potassium hydroxide was developed. This reaction proceeded under mild and transition metal-free conditions through an addition/elimination cascade process. Both aromatic and aliphatic vinyl selenones and various mono-, bi- and tri-cyclic azoles can be tolerated and give terminal N-vinyl azoles in
开发了一种在氢氧化钾存在下使用乙烯基硒酮和唑类合成 N-乙烯基唑类的新方案。该反应在温和且不含过渡金属的条件下通过加成/消除级联过程进行。芳香族和脂肪族乙烯基硒酮以及各种单环、双环和三环唑都可以耐受,并以中等至高产率产生末端 N-乙烯基唑。还提出了一种合理的机制。
