A practical and efficient approach for the synthesis of selenol and thiol esters is described via the reaction of acyl chlorides with diselenides or disulfides in the presence of Zn dust catalyzed by inexpensive CoCl2·6H2O This protocol tolerates a wide range of substrates, including aromatic and aliphatic acyl chlorides, with a variety of sensitive functional groups to afford the respective products
在廉价的 CoCl 2 ·6H 2 O催化下,通过酰氯与二硒或二硫化物的反应,描述了一种合成硒醇和硫醇酯的实用且有效的方法。该协议适用于广泛的底物,包括芳香族和脂肪族酰氯,具有各种敏感的官能团,以良好的收率提供相应的产品。此外,该方法还扩展到使用酸酐作为底物。此外,通过钯/铜体系催化的末端炔烃的硒羰基化,获得的硒醇酯可以很容易地转化为乙烯基硒酮。
