Selective Reductive Coupling of Nitro Compounds with Aldehydes to Nitrones in H₂ Using Carbon‐Supported and ‐Decorated Platinum Nanoparticles

Nitrones were synthesized in high yields directly from nitro compounds, aldehydes, and H 2 using carbon‐decorated platinum nanoparticles. The high selectivity for nitrone synthesis contrasts that of common supported metal catalysts and corresponds to an increase from roughly 6 to 97 %. The catalytic performance is tuned by precise control of the structure of the active sites and the characteristics of the support.
