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.
