Abstract: Herein, we report the first diaryliodonium salts promoted multicomponent 1,2,3-trifunctionalization of alkynes, where both the acetylenic bond and the adjacent nonactivated propargylic C(sp3)-H bond were functionalized synergistically to generate α-arylated enones with high chemo-, regio-,… read more here.
