In this work, we have developed a new chemical reagent 1 to access methyl sulfones. Its reaction with various N,N-and N,Cbis-nucleophiles leads to the formation of the previously unknown methyl sulfones. This transformation works efficiently on a milligram, gram and even multigram scale. Analogous strategy can also be used to construct alkyl-, CHF2-, CF3-and even bicyclo [1.1.1]pentane-containing derivatives. These compounds have been comprehensively characterized. They also have been demonstrated to have a high potential for use in medicinal chemistry and coordination chemistry.
