2-Arylindoles: A new entry to transition metal-free synthesis of 2-aminobenzophenones
Yu, Jin,Moon, Hye Ran,Min, Beom Kyu,Kim, Jae Nyoung
, p. 893 - 897 (2016)
Various 2-aminobenzophenones were synthesized from readily available 2-arylindoles in DMSO under O2 balloon atmosphere. The synthesis was carried out without the aid of a transition metal catalyst or moisture-sensitive organometallic reagents from 2-arylindoles.
Tetrazoles: XXXV. Synthesis of 3H-1,3,4-Benzotriazepines from 5-Aryltetrazoles

, p. 1767 - 1770 (2007/10/03)
Reaction of 5-aryltetrazoles with N,N′-bis(p-tolyl)terephthalimidoyl dichloride under conditions of phase-transfer catalysis yields isomeric N-imidoyltetrazoles whose thermolysis results in formation of 3H-1,3,4-benzotriazepines. The latter are hydrolyzed by the action of hydrochloric acid to afford terephthalic acid and the corresponding aminobenzophenone.
