Angew Chem Int Ed Engl. 2013 Mar 25;52(13):3765-9. doi: 10.1002/anie.201300021. Epub 2013 Feb 25.

Abstract

A new strategy for iminium ion isomerization was applied to the direct, redox-neutral α-alkynylation of amines. Cu(II) 2-ethylhexanoate was identified as the optimal catalyst for this three-component coupling reaction of secondary amines, aldehydes and alkynes.
