Pellicular resin-supported dimethyl sulfoxide: An effective catalyst in ‘three-phase’ reactions
Pellicular resins have been prepared from polypropylene spherical beads after successive peroxidation by ozone, grafting of poly(styrene-co-chloromethystyrene) by radical polymerization, and finally a chemical two-step modification, to yield anchored sulfoxide groups. Under three-phase catalysis conditions, pellicular resin sulfoxides, —CH2SOCH3, display higher catalytic activity in alkylation reaction than conventional gel-type or macroporous resins carrying the same amount of sulfoxide groups. The catalytic activity of pellicular resin sulfoxides was found to depend on their composition; they were found to be more effective than the low-molecular dimethylsulfoxide analogue.
