Abstrakt: [45][46][47] Herein, we report a visible-light-induced C(3) difluoroalkylation of quinoxalin-2(1 I H i )-ones B 1 b with these difluoroiodane(III) reagents under catalyst-free conditions (Scheme 1, equation 7). The readily accessible reagents and the mild reaction conditions make this reaction an alternative and practical strategy for the synthesis of C3-difluoroalkylated quinoxalin-2(1 I H i )-ones.
