BORON COMPLEXATION STRATEGY FOR USE IN MANIPULATING 1-ACYLDIPYRROMETHANES

摘要

A method of making a metal complex comprises combining a 1-monoacyldipyrromethane with a compound of the formula R¹R²MX, wherein M is boron, R¹ and R² are each independently organic substituents; and X is an anion leaving group; to produce a metal complex of the formula DMR¹R² wherein DH is a 1-monoacyldipyrromethane. The methods and complexes are useful for the purification and synthesis of dipyrromethanes and porphyrins.
