Ethene-linked nucleoside derivatives of porphyrins and chlorins have b
een synthesized by palladium-catalysed coupling between acetylated 5-c
hloromercuriuridine and various vinylporphyrins and vinylchlorins. The
formation of both the trans-(e.g. 22, 24, 29) and gem-(e.g. 23, 30) i
someric products was usually observed in these coupling reactions, and
ratios of these isomers were dependent upon the particular substrate
employed.
