Synthetic route to meso-tetra hydrocarbyl or substituted hydrocarbyl porphyrins and derivatives
Patent
·
OSTI ID:6047121
The hydroxyl group in a pyrrolic compound having in the 2-position thereof a group having the formula R(OH)CH-R is hydrocarbyl or substituted hydrocarbyl, is replaced by a group, for example a p-nitrobenzoate group, having better leaving properties than those of hydroxyl for a subsequent self-condensation and cyclization of the pyrrolic compound to form a meso-hydrocarbyl or meso-substituted hydrocarbyl porphyrin.
