Sp. Zheng et al., THE SYNTHESIS AND STRUCTURE OF A NEW-TYPE OF AROMATIC HETEROCYCLIC MACROCYCLE - IV - SYNTHESIS OF A 1,3,4-OXADIAZOLE-CONTAINING AZOMACROCYCLE, Journal of heterocyclic chemistry, 35(2), 1998, pp. 275-277
A novel azomacrocycle containing the 1,3,4-oxadiazole ring has been pr
epared from bis[3-(4-hydroxyphenylazo)phenyl]-1,3,4-oxadiazole 5 and 2
,5-bis(2-chloromethlylphenyl)-1,3,4-oxadiazole 8. The coupling reactio
n between the diazonium salt 4 and bisphenol A has been reported.
