[MoO3(2,2′–bipy)](n) catalyzed oxidation of amines and sulfides
Autor: Marta Abrantes, Fabrizio Cavani, Isabel S. Gonçalves, Carolina Vurchio, Irene Tosi, Martyn Pillinger, Franca M. Cordero, Alberto Brandi
The polymeric catalyst [MoO3(2,2′–bipy)]n has been employed in the oxidation of secondary amines to nitrones, and sulfides to sulfoxides or sulfones, using tert–butylhydroperoxide (TBHP) as the stoichiometric oxidant. Whereas the oxidation of a
