  • BORON COMPLEXATION STRATEGY FOR USE IN MANIPULATING 1-ACYLDIPYRROMETHANES
    Publication number: 20080071093
    Abstract: 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.
    Type: Application
    Filed: August 29, 2007
