The development of addition reactions wherein the product is the simple sum of the reactants plus anything else (only needed catalytically) constitutes an important goal for enhanced synthetic efficiency. The C−H bond of terminalalkynes (the donor alkynes) can be added to either terminalalkynes (self-coupling) or activated internal alkynes (cross-coupling) (the acceptor alkynes) in the presence of
