Metal-free synthesis of propargylamines via light-mediated persulfate activation and phase-transfer catalysis

Org Biomol Chem. 2024 Mar 20;22(12):2359-2364. doi: 10.1039/d4ob00218k.

Abstract

We present a metal-free method to synthesize secondary and tertiary propargylamines from primary and secondary amines and alkynes using light-mediated persulfate activation and phase-transfer catalysis. Our method explores a tandem oxidative coupling/alkynylation reaction for the generation of diverse compounds, highlighting the sustainability of the process and its wide scope.
