Remarkable catalytic activity of ultra small free-CeO2 nanoparticles in selective carbon-carbon bond formation reactions in water at room temperature

13.05.2015 | Subhash Banerjee, New Journal of Chemistry, 2015

A simple and efficient protocol for selective bis-Michael addition and mono allylation of active methylene compounds has been demonstrated using capping agent free ultra-small sized (~ 5 nm) cerium oxide nanoparticles (free-CeO2 NPs) as reusable catalyst in water at room temperature. Significant ...
