Abstract

We describe the synthesis of three new isomeric 1, 3, 4-oxadiazole–pyridine hybrids, namely: 2, 6-, 3, 5-and 2, 4-bis [2-(4-tert-butylphenyl)-1, 3, 4-oxadiazol-5-yl] pyridine,(PDPy- 2, 6, PDPy-3, 5 and PDPy-2, 4, respectively) and a 1, 3, 4-oxadiazole–pyrimidine hybrid, namely: 2, 5-bis [2-(4-tert-butylphenyl)-1, 3, 4-oxadiazol-5-yl] pyrimidine (PDPmDP). The X- ray crystal structures are reported for PDPy-2, 4 and the known phenylene analogue 1, 3- ...
