Ag nanoparticle-catalyzed aerobic oxidation of benzyl alcohols in basic DMSO gave efficient formation of styryl ethers, featuring single carbon transfer and C═C and C–O bond formation. A deuterium labeling experiment established that DMSO was the carbon source. Further experiments showed the reaction proceeded through a styryl sulfoxide intermediate originating from basic DMSO and transient benzaldehyde
