Chloroacetylenephosphonates react with 1-substituted tetrazole-5-thiones in anhydrous acetonitrile to form fused heterocycles, viz., 3-substituted 6-(dialkoxyphosphoryl)-3H-thiazolo[3,2-d]tetrazol-7-ium chlorides, along with a small amount of compounds having a linear structure, viz., Z-dialkyl 1,2-bis[(1-methyl(phenyl)-1H-tetrazol-5-yl)sulfanyl]ethenyl}phosphonates.
