Activity of ceria and ceria-supported gold nanoparticles for the carbamoylation of aliphatic amines by dimethyl carbonate

Juárez Marín, Raquel; Corma Canós, Avelino; García Gómez, Hermenegildo (International Union of Pure and Applied Chemistry, 2011-09-19)

Aliphatic amines react sluggishly with dimethyl carbonate (DMC) to give a mixture of N-methylation and carbamoylation. Nanoparticulated ceria as catalyst increases, in general, conversion and selectivity toward carbamoylation. ...
Continuous flow carbamoylation of aniline by dimethyl carbonate using a microreactor coated with a thin film of ceria supported gold nanoparticles

Juárez Marín, Raquel; Pennemann, Helmut; García Gómez, Hermenegildo (Elsevier, 2011-01-10)

Selective carbamoylation of aniline by dimethyl carbonate has been performed under continuous flow using a microreactor having 10 mu m microchannels and 4 ml of total volume. Nanoparticulated ceria and gold nanoparticles ...
