An Improved Approach tomeso-Substituted 1,9-Dicyanodipyrrolylmethanes
摘要:
A series of meso-substituted 1,9-dicyanodipyrrohylmethanes and phenylene-bridges bis-dipyrrolylmethanes containing one / and two phenyl bridges have been prepared from condensation of 2-cyano-3,4-dialkylpyrrole 1 with various aromatic aldehydes.

Porphocyanines bearing phenyl substituents at both or one of the two available mesopositions have been synthesised. Derivatives have also been synthesised with substituents on the phenyl rings and both alkyl and unsubstituted pyrrolic beta-positions.
