A nucleophilic aromatic substitution via a new and facile cesiumfluoridecatalyzed synthetic approach to get 5-aryloxy-1-phenyl-1H-tetrazoles was developed. Dual usage of cesiumfluoride as a nucleophilic catalyst as well as an electrophilic catalyst afforded the desired products at room temperature in a short reaction time without purification in high yields. This simple but useful reaction may be
