The reaction of enynes with aldehydes in the presence of a catalytic amount of [RhCl(cod)](2)/dppp results in the Pauson-Khand-typereaction without the use of gaseous carbon monoxide to give bicyclic cyclopentenones in high yields (14 examples). Aldehydes serve as a source of carbon monoxide, and their carbonyl moiety is transferred to enynes, resulting in the formation of the carbonylated products
在催化量的 [RhCl(cod)](2)/dppp 存在下,烯炔与醛的反应会导致 Pauson-Khand 型反应,而无需使用气态一氧化碳,以高产率得到双环环戊烯酮 (14例子)。醛作为一氧化碳的来源,它们的羰基部分被转移到烯炔,导致形成羰基化产物。该反应代表了 CO 转移羰基化的第一个例子。
