The synthesis and characterization of three new unsymmetrical porphyrins is
reported. These porphyrins are isomers and have not been reported previous
ly. A new method was used to synthesize the porphyrins which is different f
rom the general synthetic porcedure which was developed by Adler ([1]). The
structural assignment of the three isomers was based on the elemental anal
yses, UV-Vis, IR, and (HNMR)-H-1 spectra.
