Abstract

Three's a crowd: Tri ‐ and tetrasubstituted allyl allenes can be easily accessed by this CuI ‐ catalyzed three ‐ component coupling reaction of N ‐ tosylhydrazones, terminal alkynes, and allyl halides. The reaction proceeds through a mechanism involving copper carbene migratory insertion. [ABSTRACT FROM AUTHOR]
