| Abstract: | The novel macrocyclic Schiff bases upon which were fused triazole and pyrazole units and containing N, O and S inside the macrocyclic ring as donor atoms were synthesized by condensation of appropriate bis(4‐amino‐1,2,4‐triazole‐3‐yl‐sulfanyl)alkanes 2a , 2b , 2c , 2d , 2e , 2f , 2g , 2h , 2i , 2j , 2k , 2l , 2m , 2n , 2o , 2p , 2q , 2r and pyrazoledialdehyde 3 in refluxing glacial acetic acid. The structural identities of these compounds were confirmed on the basis of spectrum. |
