Cocktail of three: A new strategy for iminium ion isomerization was applied to the direct, redox‐neutralα‐alkynylation of amines. Copper(II) 2‐ethylhexanoate [Cu(2‐EH)2] was identified as the optimal catalyst for this three‐component coupling reaction of secondary amines, aldehydes, and alkynes. MW=microwave.
