Abstract

In a previous paper1 we have described the formation of 2,5-dianilino-
1,3,4-thiadiazole and other 2,.5-diarylamino compounds fr.om 4-phenylthiosemicarbazide or other 4-arylthiosemicarbazides and diethyl cal1bonate. The same reacti,on product was also obtained by other workers when reacting 4-rphenylthiosemicarbazide with acetic acid2, concentrated sulfuric acid3, sulfur monochloride4 or with urea in amyl alcohoP. Furthermore, many reactions are known s'bairting w1th 1,6-diiphenylbithiourea5 and leading similarly to 2,5- · dianilino-1,3,4~thiaidiazole .
