efficient route for methylation and acetylation of aza-heteroarenes using PEG-400 under O2 and TsOH·H2O for the first time by tuning the reaction conditions using a different set of starting materials. The key features of the current protocol are oxidative C–O and C–C bond scission under metal-free conditions with good functional group tolerance, and a broad substrate scope. The potential applicability
