- Abstract
Alkaline salt of platinum‐incorporated heteropolyoxoniobate [Pt(Nb6O19)2]12− (Pt(Nb6)2) was fabricated and applied for N‐formylation of various amines including piperidine under CO2 and H2 atmosphere. Pt(Nb6)2 achieved the selective formation of 1‐formylpiperidine, whereas the absence of Pt species, H2, and CO2 resulted in a trace amount of the product. The structural characterization revealed that the sandwich‐type structure of Pt(Nb6)2 was transformed into Pt nanoparticles incorporated with polyoxoniobates ([Nb6O19]8−) on the NbOx bulk matrix (NbPOM‐PtNPs/NbOx) under reaction conditions. The N‐formylation of amines in the presence of CO2 and H2 proceeded by the bifunctional NbPOM‐PtNPs/NbOx where the basic sites of [Nb6O19]8− and the redox property of Pt promoted the generation of formamides.
