A modified Horner-Emmons condensation reaction has been employed in the synthesis of acetylenesubstituted porphyrins at the b-pyrrolic position. This technique was shown to have many advantages over the typically employed Sonogashira coupling method, including negating the requirement for a brominat

We have found that octasubstituted porphyrins having no substituents in the meso positions can be prepared in high yields by acid catalyzed condensation of formaldehyde with a variety of 3,4-disubstituted pyrroles. This improved procedure circumvents the need to prepare aldehyde, aminomethyl, or hyd
