Abstract
A conjugated bis-guanidinate (CBG)-supported aluminum dihydride complex catalyzes a chemoselective hydroboration of various nitriles and alkynes. The reaction leaves other reducible groups intact. Moreover, aluminum-catalyzed hydroboration is expanded to more challenging substrates such as alkene, pyridine, imine, carbodiimide, and isocyanides.
