Extended Data Fig. 1: Formation of BPI-N-RO− from BPI-N.
From: Photocatalytic C–F bond activation in small molecules and polyfluoroalkyl substances
a, Using a more symmetric variant BPI-N for intermediate study. b, Comparing the UV–visible spectra of isolated BPI-N-RO− (post basic alumina column with and without aqueous workup) with that of the crude BPI-N with nBu4NF mixture. Absorption spectrum of BPI-N is shown for reference. c, 1H-1H COSY of the isolated intermediate BPI-N-RO− (acetone-d6, 300 MHz). d, 1H-13C HSQC of the isolated intermediate BPI-N-RO− (acetone-d6, 300 MHz).
