Abstract

A step‐ and redox‐economic route toward aminoallenes from simple alkynes and N‐fluorobenzenesulfonimide (NFSI) was established via selenium‐π‐acid catalysis. This unprecedented method significantly streamlines the assembly of heterosubstituted 1,3‐propadiene motifs and is characterized by a broad functional group tolerance. The facile synthesis of aminoallenes, accomplished by a ...
