N-methylation of indole and O-methylation of phenol have been developed using MgO as a heterogeneous, inexpensive, easily available, recyclable solid base and dimethyl carbonate as a green methylating reagent.
A novel amine modified meso Al2O3@MCM-41 catalyst was investigated for the synthesis of formamides from 1°/2° aliphatic as well as aromatic amines with CO2, using DMAB.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
