Abstract

The use of TMPLi base in a pentane/THF mixture at 25C or use of a metal alkoxide base in dioxane at elevated temperature enable base-mediated, transition-metal-free alkynylations of aryl chlorides that proceed via benzyne intermediates. Fluoro, trifluoromethyl, silyl, cyano, and alcohol functionalities are compatible with the reaction conditions.
