Abstract
Fluorinated asymmetric aryl ketones represent a pivotal class of organic synthesis intermediates, which have garnered widespread application in the realms of organic chemistry, materials science, and drug discovery. Herein, we report a pioneering nucleophilic aromatic substitution (SNAr) reaction involving aryl aldehydes and polyfluoroarenes, elegantly catalyzed by N-heterocyclic carbene (NHC). This innovative strategy yields bis(hetero)aryl ketone products in yields ranging from moderate to exceptional (40–83%), all achieved under gentle conditions, devoid of both transition metals and directing groups. The versatility of this method is underscored by its compatibility with a broad spectrum of substrates, particularly exhibiting remarkable resilience toward alkoxy functional groups. Notably, we have successfully transformed an array of biologically active molecules, crafting a series of their corresponding derivatives with precision.
期刊介绍:
Synthetic Communications presents communications describing new methods, reagents, and other synthetic work pertaining to organic chemistry with sufficient experimental detail to permit reported reactions to be repeated by a chemist reasonably skilled in the art. In addition, the Journal features short, focused review articles discussing topics within its remit of synthetic organic chemistry.
