Abstract

An ortho-dimethyl substituted meso-tetrakisarylporphyrin prefunctionalized with triflate groups was prepared in good yield from an accessible 2, 6-dimethyl-4-(triflyloxy) benzaldehyde. This porphyrin is an interesting building block, which could directly be engaged in Suzuki cross-coupling reactions, to be further tetra functionalized with 3-pyridyl ligands in yields equal or above 85%. The porphyrin core of the various compounds ...
