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

摘要

Nitrones were synthesized in high yields directly from nitro compounds, aldehydes, and H2 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.
