Addition of 1-substituted tetrazole-5-thiols to ethyl propiolate and phenylacetylene was studied. It was found that Pd(II) salts in the presence of strong acids are effective catalysts for this reaction: the S-adducts can be obtained at relatively low temperatures in high yields. The mechanism of this reaction was suggested.
