Rapid Aryne-Enabled Aryl Functionalization via Mechanically Assisted Microscale Mixing

Abstract

Herein, we demonstrate that arynes can be generated and trapped efficiently through mechanically assisted microscale mixing on a standard vortex mixer. Brief vortex agitation enables ultra-fast generation and interception of these highly reactive intermediates with N-, O-, S-, and C-nucleophiles within 1 min, therefore providing a low-energy-solvent minimized approach for aryl functionalization without the need for inert atmosphere, heating, or bulk solvent.
