  2-Sulfinyl Oxetanes: Synthesis, Stability and Reactivity

  摘要：

  The synthesis of 2-sulfinyl oxetanes is described by a C-C bond-forming cyclisation strategy. Oxetanes bearing electron-poor aryl sulfoxides are shown to be viable targets using this strategy. We report investigations into the sulfoxide magnesium exchange on 2-sulfinyl oxetanes, which resulted in products formed via ligand exchange and ligand coupling pathways. The sulfinyl oxetanes can be readily oxidised to the sulfonyl oxetanes.

  The SN2 reactions having a symmetrical transition state were studied in a dipolar aprotic solvent. A good Hammett correlation was found for the chlorine isotopic exchange reactions in acetonitrile between tetraethylammonium chloride and three types of substituted methyl chlorides, 2-arylethyl chlorides, chloromethyl aryl ethers, and chloromethyl aryl sulfides. The reaction constant was positive for
