Porphyrin Synthesis Using Clays. Taking Advantage of Statistical Product Distributions

Article abstract of DOI:10.1246/cl.1993.449

Solid acids such as the K10 montmorillonite are useful for preparation of porphyrins from pyrrole condensed with aldehydes.Combining the use of two different aldehydes A and B with unequal, statistical proportions of A and B allows maximization of the relative amount of the desired mixed porphyrin.
