Description
A high-yielding procedure for selective monoiodination of 2,2'-dihydroxy-1,1'-binaphthyl (BINOL) is reported. 6-Iodo-2,2'-dipivaloyloxy-1,1'-binaphthyl, obtained in three steps starting from BINOL in 88% overall yield, proved to be a highly efficient substrate in various palladium-catalyzed coupling (Stille, Heck, Sonogashira, and Suzuki coupling) and carbonylation reactions compared to the analogous 6-bromo derivative.
