Palladium-catalyzed Kumada Coupling Reaction of bromoporphyrins with silylmethyl Grignard reagents: Preparation of silylmethyl-substituted porphyrins as a …
We have developed an efficient method for preparing silylmethyl-substituted porphyrins via the palladium-catalyzed Kumada cross-coupling reaction of bromoporphyrins with silylmethyl Grignard reagents. We demonstrated the synthetic utility of these silylmethylporphyrins as a multipurpose synthon for fabricating porphyrin derivatives through a variety of transformations of the silylmethyl groups, including the DDQ-promoted ...
