to catalyze the addition of nitrogen nucleophiles to terminalalkynes under mild conditions to stereoselectively form the Z-enamide or Z-enimide products. Various secondaryamides and imides could be added across the triple bond of a range of aliphatic and aromatic alkynes. The new bimetallic catalyst system sets new standards with regard to scope and selectivity for the synthesis of Z-configured anti-Markovnikov
