The author of 《A Convenient Synthesis of 1,5-Fused 1,2,4-Triazoles from N -Arylamidines via Chloramine-T Mediated Intramolecular Oxidative N-N Bond Formation》 were Bhatt, Ashish; Singh, Rajesh K.; Kant, Ravi; Sarma, Bhupendra K.. And the article was published in Synthesis in 2019. Formula: C7H4FN The author mentioned the following in the article:
A convenient synthesis of 1,5-fused 1,2,4-triazoles from readily available N-arylamidines was reported. The reaction was efficiently promoted by chloramine-T to afford the desired products mostly in high yields and in relatively short time, through direct metal-free oxidative N-N bond formation. The mild nature of the synthesis and short reaction time are notable advantages of the developed protocol. This protocol was effective toward various substrates having different functionalities. After reading the article, we found that the author used 4-Fluorobenzonitrile(cas: 1194-02-1Formula: C7H4FN)
4-Fluorobenzonitrile(cas: 1194-02-1) is used as chemical intermediate, solvent for perfumes and pharmaceuticals, stabilizer for chlorinated solvents, HPLC analysis, catalyst and component of transition-metal complex catalysts.Formula: C7H4FN
