An efficient copper-catalyzed C–X (X = S, Se) decarboxylative coupling of alkynyl carboxylic acids with Bunte salts has been developed. The process is amenable to various alkynyl carboxylic acids and Bunte salts and is compatible with a wide range of functional groups. In addition, this catalytic reaction could also be performed with seleno Bunte salts and alkynyl carboxylic acids under the same conditions, giving the alkynyl selenosulfides in good yields. Importantly, this route avoids the use of odorous thiol or selenol starting materials.

铜催化的炔基羧酸与班特盐的C-X(X = S,Se)交叉偶联,实现无硫醇的炔基硫属元素化物的合成

已经开发了一种高效的铜催化炔基羧酸与邦特盐的C-X(X = S,Se)脱羧偶联反应。该方法适用于各种炔基羧酸和邦特盐,并且与多种官能团相容。另外,该催化反应还可以在相同条件下用硒代布氏盐和炔基羧酸进行,从而以良好的收率得到炔基硒代硫化物。重要的是,该途径避免了使用有气味的硫醇或硒醇原料。
