Synthesis of symmetrical and unsymmetrical 1,3,4-oxadiazoles and their interconversion to 1,3,4-thiadiazoles and 1,2,4-triazoles
A new class of symmetrical and unsymmetrical 1,3,4-oxadiazoles was prepared. Interconversion of oxadiazoles to thiadiazoles and triazoles was effected in the presence of appropriate nucleophiles.
