efficient carbonylation procedure for the carbonylative cross-coupling of aryl thianthrenium salts with aromatic alkynes. Various useful alkynones were produced in moderate to excellent yields under mild conditions. Notably, among the various tolerated functional groups, the bromide group can be maintained, which is ready for further coupling reactions.
炔酮是有价值的化合物,在各个领域都有应用。在这项工作中,我们开发了一种有效的羰基化方法,用于芳基噻啉鎓盐与芳族炔烃的羰基化交叉偶联。在温和条件下以中等至优异的产率生产了各种有用的炔酮。值得注意的是,在各种耐受的官能团中,可以保留溴基团,为进一步的偶联反应做好准备。
