Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>On the basis of the mechanism of Baeyer–Villiger (B‐V) oxidation, a bifunctional catalyst based on tetra(4‐sulfonato‐phenyl)porphinato‐cobalt(II) anion (CoTSPP) intercalated into Zn₂Al hydrotalcite (Zn₂Al‐LDH; LDH=layered double hydroxide) was designed and prepared. XRD, FTIR, DR UV/vis, TG/DTA, and SEM characterization indicate that CoTSPP molecular has been successfully intercalated into the layers of Zn₂Al‐LDH. The catalytic activity of the synthesized hybrid in the B‐V oxidation for various ketones is excellent. Control experiments indicated that the catalyst has a bifunctional role in the reactions. The protocol opens up new perspectives in the rational design of efficient catalytic systems.</p> </abstract>
