Magnesium oxide as a heterogeneous and recyclable base for the N-methylation of indole and O-methylation of phenol using dimethyl carbonate as a green methylating agent

Abstract

<italic>N</italic>-methylation of indole and <italic>O</italic>-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.
