Abstract
The mechanism of the cyclization of meso-(1-hydroxy-2-propenyl)octaethylpor phyrin to octaethylbenzochlorin is proposed. Chlorin intermediates were iso lated, characterized and then converted to octaethylbenzochlorin. A rhodino benzochlorin was isolated on demetallation of Ni coprobenzochlorin with met hane sulfonic acid and its structure was confirmed by X-ray crystallography . (C) 2000 Elsevier Science Ltd.
