A highly efficient and facile metal-free, one-pot reaction has been developed to afford diversely substituted N-arylbenzimidazoles through chemoselective in situ generation of N,N′-diarylamidines from arenediazonium salts, nitriles, and free anilines. The advantages of this protocol consist of the operationally easy and simple one-pot procedure under metal-free and mild conditions, the direct use of inexpensive and commercially available chemicals, and thus, a cost-effective and greener process.

In this work, at first, triazenes were synthesized from primary aryl amines. Afterwards, triazenes were converted into the corresponding thiophenols in one-pot using sodium sulfide in acidic media, by in situ generation of diazonium counterion beside hydrogen sulfide as anionic sulfur nucleophile at room temperature. The procedure can be a convenient shortcut for the preparation of thiophenols from primary aryl amines. Georg Thieme Verlag Stuttgart · New York.
Pd-catalyzed C-H activation/C-N bond formation: A new route to 1-aryl-1H-benzotriazoles
Kumar, Rapolu Kiran,Ali, Md Ashif,Punniyamurthy, Tharmalingam
supporting information; experimental part, p. 2102 - 2105 (2011/06/25)
A method for the C-H activation of aryl triazene compounds followed by intramolecular amination is described. It involves the use of a catalytic amount of Pd(OAc)2 that efficiently effects the cyclization to provide 1-aryl-1H-benzotriazoles at moderate temperature.
