Aerobic oxidation of thiols to disulfides by heterogeneous gold catalysts

Corma Canós, Avelino; Ródenas Torralba, Tania; Sabater Picot, Mª José (Royal Society of Chemistry, 2012)

Thiols are smoothly and efficiently oxidized to disulfides (RSSR) with air in the presence of gold nanoparticles supported on CeO2 in absence of solvent, as well as in aqueous solutions and neutral pH. It is shown that the ...
Sweet chiral porphyrins as singlet oxygen sensitizers for asymmetric Type II photooxygenation

Griesbeck, Axel G.; Miranda Alonso, Miguel Ángel; Uhlig, Johannes (Royal Society of Chemistry, 2011)

Carbohydrate-decorated meso-tetraarylporphyrins P-G and P-C were synthesized via Lewis-acid catalyzed condensation of acetylated carbohydrate-substituted benzaldehydes and pyrrole. Their efficiency of singlet oxygen ...
