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


ABSTRACT: 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.
