Abstract

An efficient 2,2,6,6-tetramethylpiperidinooxy (TEMPO)-mediated hydroxyfluoroalkylation of arylamines with polyfluorinated alcohols via a radical-triggered C(sp2)-H/C(sp3)-H dehydrogenative cross-coupling process was developed. This transformation features simple operation, high atom economy, broad substrate compatibility, and excellent regioselectivity, leading to a series of hydroxyfluoroalkylated arylamine derivatives. Importantly, these synthetic products were further used to evaluate the antitumor activity in cancer cell lines by Cell Counting Kit-8 assay and the outcomes indicated that some compounds show a potent antiproliferative effect.
