chlorins have been synthesized by palladium-catalysed coupling between acetylated 5-chloromercuriuridine and various vinylporphyrins and vinylchlorins. The formation of both the trans-(e.g. 22, 24, 29) and gem-(e.g. 23, 30) isomeric products was usually observed in these coupling reactions, and ratios of these isomers were dependent upon the particular substrate employed.
