HETEROCYCLIC ANALOGS OF PLEIADIENE. LVI. A NEW REACTION OF PERIMIDINES AND BENZIMIDAZOLES - DIMERIZATION UNDER THE INFLUENCE OF DILITHIOBENZOPHENONE WITH SUBSEQUENT AROMATIZATION OF ONE HETEROCYCLE AND OPENING OF THE OTHER

Pozharskii, A. F.,Smirnova, L. P.,Klyuev, N. A.,Starshikov, N. M.

, p. 1427 - 1434 (2007/10/02)

Under the influence of dilithiobenzophenone in THF 1-substituted perimidines and benzimidazoles undergo dimerization at position 2.The initially formed dilithio derivative of the bisdihydro compound then undergoes a complex transformation of the hydride disproportionation type, as a result of which one of the heterocycles on the dimer is aromatized while the other is opened.
