Aldehyde decarbonylation has been extensively investigated, primarily using noble-metal catalysts; however, nonprecious-base-metal-catalyzed aldehyde decarbonylation has been hardly reported. We have established an efficient selective aldehyde decarbonylation reaction with a broad substrate scope and functional group tolerance utilizing a heterogeneous Ni(0) nanospecies catalyst supported on CeO2.
醛脱羰已被广泛研究,主要使用贵金属催化剂;然而,几乎没有报道过非贵金属催化的醛脱羰。我们已经建立了一种有效的选择性醛脱羰反应,该反应具有广泛的底物范围和官能团耐受性,利用负载在 CeO 2上的非均相 Ni(0) 纳米物质催化剂。根据详细的催化剂表征和动力学评估,高催化性能归因于高度分散和非富电子的 Ni(0) 纳米物质,这可能抑制副反应产生酯和吸附 CO 衍生的催化转化抑制。
