title: Microwave-promoted insertion of Group 10 metals into free base porphyrins and chlorins: scope and limitations.
abstract: The scope and limitations of microwave heating as a tool for insertion of Group 10 metals into meso-tetraphenyl-porphyrin, -porpholactone, and -2,3-dihydroxychlorin derivatives are discussed. In some cases it is possible to reduce reaction times dramatically while obtaining good yields of the metallated products while in others new issues arise relating to the metal salt used as well as acceleration not only of the metallation reaction but also of byproduct formation.
