An efficient Cu-catalyzed C-H alkenylation with acyclic and cyclic vinyl boronates was realized for the first time under mild conditions. The scope of the vinyl borons and the compatibility with functional groups including heterocycles are superior than Pd-catalyzed C-H coupling with vinyl borons, providing a reliable access to multisubstituted alkenes and dienes. Subsequent hydrogenation of the product from the internal vinyl borons will lead to installation of secondary alkyls.

Cu-mediated C-H thioetherification of arenes with ethylene sulfide has been developed using a readily removable directing group. The reaction proceeded at room temperature, and a variety of sensitive functional groups including chloro, bromo, and vinyl were well tolerated. The thiolated products could be converted to the seven-membered benzoxathiepinones derivatives by a sequence of hydrolysis-lactonization reactions.

A new Cu(II)-catalyzed oxidative coupling of arenes with malonates has been developed using an amide-oxazoline directing group. The reaction proceeds via C(sp2)-H activation and malonate coupling, followed by intramolecular oxidative N-C bond formation. A variety of arenes bearing different substituents are shown to be compatible with this reaction.
Cu(II)-mediated ortho C-H alkynylation of (hetero)arenes with terminal alkynes

, p. 11590 - 11593 (2014/10/15)
Cu(II)-promoted ortho alkynylation of arenes and heteroarenes with terminal alkynes has been developed to prepare aryl alkynes. A variety of arenes and terminal alkynes bearing different substituents are compatible with this reaction, thus providing an alternative disconnection to Sonogashira coupling.
Cu(II)-mediated C-H amidation and amination of arenes: Exceptional compatibility with heterocycles

supporting information, p. 3354 - 3357 (2014/03/21)
A Cu(OAc)2-mediated C-H amidation and amination of arenes and heteroarenes has been developed using a readily removable directing group. A wide range of sulfonamides, amides, and anilines function as amine donors in this reaction. Heterocycles present in both reactants are tolerated, making this a broadly applicable method for the synthesis of a family of inhibitors including 2-benzamidobenzoic acids and N-phenylaminobenzoates.
