The study and application of transitionmetal hydrides (TMHs) has been an active area of chemical research since the early 1960s1, for energy storage, through the reduction of protons to generate hydrogen2,3, and for organic synthesis, for the functionalization of unsaturated C–C, C–O and C–N bonds4,5. In the former instance, electrochemical means for driving such reactivity has been common place since
A highly selective hydroboration of unsymmetrical internalalkynes featuring unique regioselectivity, broad substrate scope and good functional group compatibility was realized by using cobalt catalysts modified with newly developed cyclopropane-based diphosphine ligands. The current protocol enabled the synthesis of novel alkenyl borates and improved the synthetic efficiency of bioactive compounds
