catalyst for the copper-, phosphorus-, and solvent-free coupling reaction of terminal alkynes with different acyl chlorides in the presence of triethylamine as base, at room temperature and under aerobic conditions. The simple, mild, and green procedure, short reaction times, and moderate to excellent yields make this method well-suited for ynone synthesis. Graphical Abstract .
摘要在三乙胺存在下,在室温和好氧条件下,氯化钯-cryptand-22络合物是一种有效的催化剂,可用于末端炔烃与不同的酰氯的铜,磷和无溶剂偶联反应。条件。简单,温和,绿色的过程,较短的反应时间以及中等至出色的收率使得该方法非常适合于合成炔酮。 图形概要 。
