Aryl or hetaryl ethers 89, prepared from 5-chlorotetrazoles with aryloxy or hetaryloxy compounds, are easily hydrogenolyzed to give tetrazol-5-ols (tetrazolones) 91 (Scheme 65). Commonly, the reaction is carried out either using molecular hydrogen under pressure or using a hydrogen donor.[15,231] However, electrolytic hydrogenolysis leads to the formation of 5-unsubstituted tetrazoles 90.[232]
