ligand-controlled regiodivergent and stereospecific copper-catalyzed alkylboration of unactivated terminalalkynes has been developed. Anti-Markovnikov alkylboration products were obtained with dppbz as ligand; conversely, Markovnikov alkylboration products were obtained with DMAP as ligand. This reaction not only presents a direct route to construct a vinyl C(sp2)–C(sp3) bond but also provides an efficient
