Abstract
The zwitterionic 4-methoxybenzylidene derivative of thiooxalic acid hy drazide amide hydrazone 1 reacts with orthocarboxylic esters to 2,5-di substituted 1,3,4-thiadiazoles 2 and with carbon disulfide or 1,1'-car bonyldiimidazole to the corresponding 2,3-dihydro-1,3,4-thiadiazoles 4 and 5. The acyclic zwitterionic products 3 were obtained from 1 with aromatic acyl chlorides. X-Ray structural data of 2a and 2b are given. All compounds are characterized by spectroscopic data (H-1 NMR, C-13 NMR, IR).
