The Wittig reaction of methyl pyropheophorbide‐ d 2 , obtained from methyl pyropheophorbide‐ a 1 , with benzyltriphenylphosphonium bromide was performed to yield isomers 3a and 3b . The Vilsmeier reaction of nickel complex 4 or 7 with 3‐dimethylaminoacrolein in the presence of phosphoryl chloride was carried out to form 20‐ meso ‐2′‐formylvinylpyropheophorbide ‐a 5 or 8 , which was reacted with Wittig reagent to afford nickel complex isomers 6a and 6b or 9a and 9b , 10a and 10b .
