An efficient nickel-catalyzed asymmetric hydrogenation of hydrazones to chiral hydrazines has been realized with up to 99 % yield and 99.4 : 0.6 er. Deuterium labelling experiments indicated that the hydrazone substrates undergo imine-enamine tautomerizat

In the presence of a protonated cinchonine derivative, radical addition reactions proceeded efficiently, affording addition adducts in high yields with an extremely high enantioselectivity. The chiral ammonium salt was recyclable after a simple aqueous workup. The reaction provides environmentally benign reaction conditions. Copyright
