A new one-pot procedure leading to β-enaminones has been developed. The elaborated methodology involves the cascade sequencing of carbonylative Sonogashira coupling of aryl iodide with a terminal alkyne and the oxidative dealkylation of tertiary amines. The efficient syntheses of β-enaminones were performed with a Pd/DNA catalyst, with NEt₃, NPr₃ and NBu₃ used as amine sources. The catalyst was successfully recovered and used in several subsequent tests with the same results. The reaction mechanism, summarizing the activity of immobilized Pd NPs (palladium nanoparticles), was proposed.

使用三烷基胺和Pd / DNA催化剂合成β-烯胺

已经开发出一种新的一锅法，可产生β-烯胺酮。详尽的方法学涉及芳基碘与末端炔烃的羰基化Sonogashira偶联的级联测序和叔胺的氧化脱烷基。使用Pd / DNA催化剂，以NEt ₃，NPr ₃和NBu ₃为胺源，可以有效合成β-烯胺酮。该催化剂已成功回收，并用于随后的几个测试中，结果相同。提出了反应机理，总结了固定化的Pd NPs（钯纳米颗粒）的活性。
