Abstract
Abstract A convenient synthesis of a meso-tetraphenylporphyrin monoaldehyde, 1c, is reported. Condensation of this aldehyde with excess benzaldehyde and pyrrole gives the bis-porphyrin 2. A low yield of the title compound, the penta-porphyrin 3 is obtained from 1c and pyrrole in refluxing propionic acid.
