Da. Shultz et al., PREPARATION OF MESO-TETRA(4-GALVINOLPHENYL)PORPHYRIN - A BUILDING-BLOCK FOR MOLECULAR MAGNETIC-MATERIALS, Tetrahedron letters, 34(25), 1993, pp. 3975-3978
The synthesis and oxidative electrochemistry of a free-radical substit
uted metalloporphyrin are described. The porphyrin is prepared in four
steps in good yield. Oxidation at a platinum electrode shows the mole
cule undergoes five reversible one-electron transfers to a stable pent
aradical.
