Synthesis and spectra of meso-dialkyl-β-octamethylporphyrins

Condensation of bis(3,4-dimethyl-2-pyrrolyl)methane or bis(5-carboxy-3,4-dimethyl-2-pyrrolyl)methane with unbranched aldehydes CnH2n+1CHO (n= 1-7) results in formation of 5,15-dialkyl-2,3,7,8,12,13,17,18-octamethylporphyrins. Zinc complexes of the porphyrins are obtained.
