1.Methylation of l-hydroxy-5-methyl(5-phenyl)tetrazoles or their salts with methyl iodide, dimethyl sulfate, or diazomethane was effected mainly or exclusively at the O atom.2.Under the action of trimethyloxonium tetrafluoroborate, 1-hydroxytetrazoles were methylated mainly at the N atom. Salts of 1-hydroxytetrazoles form comparable amounts of products of N and O methylation with oxonium salts.3.On N-methylation of 1-hydroxytetrazoles the three N atoms may be subject to electrophilic attack to a lesser extent. |
