oxidative styryl ether formation method was developed with benzylalcohol under basic DMSO. Styryl ether was obtained after 12 hours of heating at 60–80 °C where DMSO was involved in the reaction as the extra carbon source. Control experiments indicated that both phenol and DMSO are crucial for the success of the reaction. A variety of styryl ethers were prepared smoothly frombenzylalcohols in good to excellent
A transition-metal-free protocol for the synthesis of non-terminal alkenylethers, alkenylsulfides, and N-vinylazoles fromarylaldehydes or diarylketones, DMSO and O, S, N-nucleophiles has been reported. In this protocol, 24 examples of non-terminal alkenylethers and 28 examples of non-terminal alkenylsulfides in 72–95% yields have been synthesized within 5 min. Moreover, 27 examples of non-terminal
