Pd nanoparticles were successfully encapsulated inside mesoporous silicalite-1 nanocrystals (Pd@mnc-S1) by a one-pot method. The as-synthesized Pd@mnc-S1 with excellent stability functioned as an active and reusable heterogeneous catalyst. The unique porosity and nanostructure of silicalite-1 crystals endowed the Pd@mnc-S1 material general shape-selectivity for various catalytic reactions, including selective hydrogenation, oxidation, and carbon–carbon coupling reactions.

A convenient photochemical flow protocol for the formation of aryl-carbon bonds via photogenerated phenyl cations has been developed. A wide range of phenylated products, including biaryls, allylarenes, 2-arylacetals and benzyl γ-lactones, was smoothly synthesized in satisfactory yields under metal-free conditions. The adoption of a flow reactor often allowed us to adopt higher concentrations of substrates and shorter irradiation times compared to those usually employed in batch systems.

Three methylthio and/or methylsulfinyl substituted benzils (2, 6 and 7) have been synthesized on photo- or thermochemical routes, respectively.Photodecarboxylation of some new different substituted mesityl benzoates (1a-e) leads to hindered biphenyls (3a-e) accompanied sometimes by aldehyde (4a-c) and benzil formation (2) due to compatitive α-cleavage and subsequent stabilization processes of such generated free aroyl radicals.A short summary on constitutional conditions for intramolecular photoredox reactions of ortho functionalized aryl sulfinyl compounds is presented. - Keywords: Photodecarboxylations, α-Cleavages, Photoredox Reactions, Sulfoxides
