The Synthesis Of (1,3,4-Oxadiazole-2,5-Diyl) Dibenzoic Acids and Their Thiadiazole Analogues
Javaid, Khalid,Smith, David M.
, p. 985 - 997 (2007/10/02)
The title compounds are best prepared by oxidation of the corresponding 2,5-ditolyl-1,3-4-oxadiazole or -thiadiazole, and are most easily characterised by the 13C n.m.r. spectra of their di-potassium salts.
