increase has led to a range of useful strategies for installing a S(VI) functionality into complex organic molecules. Conventional synthetic methods for forming α-substituted sulfonimidoyl motifs rely on late-stage modifications at sulfur and involve multistep routes. We report the development of an efficient and generalmethod for the synthesis of various α-arylated sulfoximines through a selective S-alkylation

We describe here the facile construction of sterically hindered tertiary alkyl ethers and thioethers via the Zn(OTf)2-catalyzed coupling of alcohols/phenols with unactivated tertiary alkyl bromides and the Cu(OTf)2-catalyzed thiolation of unactivated tertiary alkyloxalates with thiols. The present protocol represents one of the most effective unactivated tertiary C(sp3)–heteroatom bond-forming conditions
