2-Mono- and 2,5-bis[bis[(4-dimethylamino)phenyl] hydroxymethyl] substi
tuted furan, thiophene and N-methylpyrrole were synthesized by mono- a
nd dilithiation of furan, thiophene and N-methylpyrrole, respectively,
and subsequent reaction with Michler's ketone. The title compounds de
velop black or dark-blue colors in acidic media.
