Direct C–H fluorination/heteroarylation of oxindoles with quinoxalin-2(1H)-ones using Selectfluor

Herein, we present an efficient and feasible strategy for direct C–H fluorination and heteroarylation of oxindoles on the C-3 position having a C(sp 3 )–H bond with quinoxalin-2(1 H )-ones based on a radical coupling reaction via Selectfluor.
