Synthesis of 2,6-diaryl--triazolo-1,3,4-thiadiazoles
Prasad, V S R,Reddy, K Kondal
, p. 435 - 436 (2007/10/02)
Reaction of 2-amino-5-aryl-1,3,4-thiadiazoles (1) with aryl cyanides inthe presence of anhydrous aluminium chloride leads to N-2-(5-aryl-1,3,4-thiadiazolyl)arylamidines (2).These (2) on oxidative cyclisation with lead tetraacetate yield 2,6-diaryl-
