Reacts with phenols in the presence of base (K2CO3-acetone) to form the 5-aryloxy-1-phenyltetrazoles, hydrogenolysis of which over Pd provides a mild procedure for replacement of phenolic OH by H: J. Am. Chem. Soc., 88, 4271 (1966); Org. Synth. Coll., 6, 150 (1988). Improved results have been obtained by catalytic transfer hydrogenolysis in the presence of hydrazine as H-donor: Tetrahedon Lett., 21, 4747 (1980)./n
