CARBENE INSERTION INTO X-H BONDS PROMOTED BY PHTHALOCYANINE COMPLEXES
Résumé
The carbene insertion to X-H bonds (X = N, S, C, Si…) is a powerful synthetic strategy to access elaborated organic compounds. These versatile reactions rely on the use of porphyrin-based catalysts and involve carbene-metal active species . Metallophthalo-cyanines (MPc) have been often considered as porphyrin analogues but their catalytic properties are often different from those of the porphyrin counterparts. While MPc are efficient catalysts for oxidation, they have been rarely explored for catalytic carbene transfer reactions. Given the similarity of oxidizing oxo species with isoelectronic carbene intermediates and the high efficiency of phthalocyanine complexes in oxidation, MPc deserve a more careful evaluation in the carbene transfer reactions.
