Non-transition Metal-Mediated Diverse Aryl–Heteroatom Bond Formation of Arylammonium Salts

Summary: Aryl–heteroatom (C–X) bonds ubiquitously exist in organic, medicinal, and material chemistry, but a universal method to construct diverse C–X bonds is lacking. Here we report our discovery of a convenient and efficient approach to construct various C–X bonds using arylammonium salts as the substrate via an SNAr process. This strategy features mild reaction condition, no request of transition metal catalyst, and easy formation of various C–X bonds (C–S, C–Si, C–Sn, C–Ge, C–Se, C–N). The method was successfully applied to a late-stage functionalization of an existing antibiotic drug, to a Clickable reaction of NBD-based ammonium salt as turn-on fluorescent probe to recognize L-cysteine and homocysteine, and to the synthesis of a DNA encoded library (DEL) bearing different C–X bonds.: Organic Chemistry; Organic Synthesis; Chemical Reaction Engineering Subject Areas: Organic Chemistry, Organic Synthesis, Chemical Reaction Engineering
