| Abstract: | 1-Chloroacetylene-2-phosphonates react with 1-substituted 5-thio-1H-1,2,3,4-tetrazoles in anhydrous acetonitrile to form new fused heterocycles, 6-(dialkoxyphosphoryl)-3H-1,3]thiazolo3,2-d]1,2,3,4]tetrazol-7-ium chlorides, with a small quantity of Z-dialkyl (1,2-bis{1-amino(methyl/phenyl)-1H-tetrazol-5-yl]sulfanyl}ethenyl)phosphonates. |
| Keywords: | Chloroacetylenephosphonates Thiazolotetrazole Heterocyclization Phosphorylated thiazolotetrazoles Zwitterions 15N NMR [1 2-Bis(thiotetrazolyl)sulfanyl]alkenephosphonates |
