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.
