Metal trifluoromethanesulfonates [M(OTf)(n); M = Sc, Zr, In] catalyse the Friedel-Crafts alkenylation of arenes using alkynes, including internal alkynes, to give, through an alkenyl cation intermediate, 1,1-diarylalkenes in high to excellent yields.
Copper-Catalyzed Hydroarylation of Internal Alkynes: Highly Regio- and Diastereoselective Synthesis of 1,1-Diaryl, Trisubstituted Olefins
Kortman, Gregory D.,Hull, Kami L.
, p. 6220 - 6224 (2017/09/15)
The copper-catalyzed hydroarylation of internal, unsymmeric alkynes is presented. Trisubstituted alkenes are obtained as single diastereomers in good to excellent yields and excellent regioselectivities. The scope of the reaction is presented with respect to alkyne and aryl iodide coupling partners. Initial mechanistic experiments indicate a hydrocupration event followed by a two-electron oxidative addition/reductive elimination pathway.
