Effect of degree of β-chlorination on photocatalytic activity of meso-tetraphenylporphyrin under homogeneous and nanoscale heterogeneous conditions: Chlorination vs. bromination

A supramolecular aluminium-based molecular catalyst for water oxidation into H2O2in saline water

“…The splitting pattern is in good agreement with the similar metalloporphyrins reported in the literature. 23 With the collective analysis of experimental results, we propose a plausible chlorination pathway for AlTPyP, as shown in Scheme 1.…”

Oxidative Coupling of Coumarins by Blue‐LED‐Driven in situ Activation of Horseradish Peroxidase in a Two‐Liquid‐Phase System

“…In addition, compound 1 is oxidized to the corresponding hydroperoxide 2 under blue‐LED driven condition by direct insertion of singlet oxygen at the tertiary α‐ethereal carbon atom (Figure 1), without formation of radical species [36] . The applications of blue‐LED in photochemistry has been reported, and the role of photosensitizers, such as meso ‐tetraphenylporphyrin ( meso ‐TPP) and iridium derivatives, adequately discussed [37–39] . Inspired by the ability of HRP to catalyze oxidative reactions using organic peroxides as alternative to H 2 O 2 , [40] we set up a novel blue‐LED driven 2LPs for the selective coupling of coumarins to bicoumarins.…”
