Preparation of meso-Silylporphyrins via Nickel-Catalyzed Coupling of meso-Brominated Ni(II) Porphyrins with Silylzinc Reagents
摘要:
In this paper, we developed a technique for the nickel-catalyzed coupling of meso-brominated Ni(II) porphyrins with silylzinc reagents in order to prepare meso-silyl-substituted Ni(II) porphyrins. Porphyrin silylation occurs under mild conditions and exhibits both excellent substrate generality and functional group compatibility.
