摘要：
A resolution-free route to chiral 2.2'-bis(pyridin-2-yl)-1.1'-binaphthyl ligands 2 was developed for the first time based on the photochemical CpCo(CO)(2)-mediated cycloaddition reaction of enantiopure 2.2'-dicyano-1.1'-binaphthyl 3 with 1.6-heptadiyne. 1,7-octadiyne, 1,8-nonadiyne, and 2.8-decadiyne.
