Visible-Light-Mediated Stereoselective 1,2-Iodoalkylation of Alkynes

Liu, Jie-Jie,Lan, Ling,Gao, Yu-Ting,Liu, Qi,Cheng, Liang,Wang, Dong,Liu, Li

, (2019)

A visible-light-mediated and photocatalyst/initiator-free addition to alkynes has been developed. An atom transfer radical addition (ATRA) mechanistic afforded a broad scope of valuable iodo-substituted alkenyl derivatives with high E/Z-selectivities, which are versatile intermediates for the synthesis of various tri- and tetra- substituted alkenes. (Figure presented.).
