Water-soluble polymer anchored peroxotitanates as environmentally clean and recyclable catalysts for mild and selective oxidation of sulfides with H2O2 in water

K Ahmed, G Saikia, S Paul, SD Baruah, H Talukdar… - Tetrahedron, 2019 - Elsevier
Anchoring of peroxotitanium (pTi) species to linear water-soluble acrylic acid based
polymers, poly (sodium acrylate)(PA) and poly (sodium methacrylate)(PMA) led to the
successful synthesis of a pair of new, water-tolerant and recyclable catalysts of the type [Ti 2
(O 2) 2 O 2 (OH) 2] 4-—L (L= PA or PMA), highly effective in chemoselective sulfoxidation of
organic sulfides with 30% H 2 O 2 in aqueous medium at ambient temperature. The catalytic
protocol is high yielding (TOF up to 11,280 h− 1), operationally simple as well as …
