Abstract: (NHC)-Cu-catalyzed C(sp)-C(sp3) bond formation has been successfully achieved under mild conditions. Nonactivated alkyl triflates, which could be easily derived from alcohols, were utilized as C-O electrophiles. Mechanistic studies suggested that copper acetylide was the active… read more here.
