Selective reductive coupling of nitro compounds with aldehydes to nitrones in H2 using carbon-supported and decorated platinum nanoparticle

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.
