Triethyloxonium tetrafluoroborate/l,2-dimethoxyethane -a versatile substitute for trimethyloxonium tetrafluoroborate in 0-methylation reactions

The triethyloxonium tetrafluoroborate/l,2-dimethoxyethane (TEO/DME) mixture is a versatile and cheap substitute for trimethyloxonium tetrafluoroborate in O-methylations of pyrrolin-2-ones, quinolones, acridones, and 1-oxo-β-carbolines. Undesired O-ethylat
