LITHIATION OF THE DIMER OF 3-BROMO-6-DIMETHYLAMINO-1-AZAFULVENE. EFFICACIOUS SYNTHESIS OF 4-MONO- AND 4,5-DISUBSTITUTED PYRROLE-2-CARBOXALDEHYDES.

The dimer 1a of 3-bromo-6-dimethylamino-1-azafulvene, is shown to function as a formal equivalent of 4-lithio- or 4,5-dilithiopyrrole-2-carboxaldehyde and consequently it is a progenitor, par excellence, of 4-mono- and 4,5-disubstituted pyrrole-2-carboxaldehydes.
