The synthesis of 1,2,4-triazolium
tetrafluoroborates under electrochemical
conditions is reported. The reaction is performed with stoichiometric
amounts of HBF4, which converts starting materials to their
corresponding cationic forms due to protonation. As a result, sufficient
conductivity is gained in MeOH, CD3OD, and EtOH, and no
additional supporting electrolyte is required. Agrochemical fungicide,
(±)-triticonazole (1), is transformed in this manner
into 2a, an O-methylated potential intermediate
involved in the metabolism of 1, in 42% yield on a gram
scale.
