New synthesis of meso-free-[14]triphyrin(2.1.1) by McMurry coupling and its derivatization to Mn(<scp>i</scp>) and Re(<scp>i</scp>) complexes

Abstract

The metal-free and meso-free [14]triphyrin(2.1.1) compound was successfully prepared based on the intramolecular McMurry coupling reaction of diformyl-tripyrrane in 16% yield, and was converted to the bowl-shaped Mn(I)(TriP)(CO)(3) and Re(I)(TriP)(CO)(3).
