Minisci-type alkylation of electron-deficient heteroarenes has been a pivotal technique for medicinal chemists in the synthesis of drug-like molecules. However, such transformations usually require harsh conditions (e.g., strong acids, stoichiometric amount of oxidants, elevated temperatures, etc.). Herein, by utilizing photoredoxcatalysis, a highly-selective alkylation method using heteroaryl sulfones

syntheses of bidentate (see 6 and 12), bis‐bidentate (7, 10, and 13) up to oligo‐bidentate (see 11 and 14) diheteroarylamine‐based N,N‐ligands are reported (Tables 2, 4, and 5). In the course of investigations on heteroaromatic (CN)‐bond formations, a protocol for the Pd‐catalyzed mono‐ and diamination of 2,6‐dichloropyridine (1) and 4,6‐dichloropyrimidines 5 with heteroaren‐2‐amines 2 and pyrimidine‐4

based probe 8 for the selective labeling of MIF and MIF2. This enabled monitoring of the translocation of MIF2 from the cytoplasm to the nucleus upon methylnitronitrosoguanidine stimulation, which indicates a nucleaseactivity for MIF2 on human genomic DNA. Thus, we provide a tool for MIF and MIF2 localization study, as well as demonstrate a nucleaseactivity for MIF2.
