Abstract

The cyclization of 4-substituted 1-arylacetyl- and 1-aryloxyacetylthiosemicarbazides and also the potassium salt of (4-bromophenoxy)acetodithiocarbazinic acid in the presence of base gives the novel 3-arylmethyl- and 3-aryloxymethyl-5-mercapto-1,2,4-triazoles and, in the presence of concentrated H2SO4, the novel 5-substituted 2-arylmethyl- and 2-aryloxymethyl-1,3,4-thiadiazoles.
