Milled Dry Ice as a C1 Source for the Carboxylation of Aryl Halides

Abstract

AbstractThe use of carbon dioxide as a C1 chemical feedstock remains an active field of research. Here we showcase the use of milled dry ice as a method to promote the availability of CO2 in a reaction solution, permitting practical synthesis of arylcarboxylic acids. Notably, the use of milled dry ice produces marked increases in yields relative to those obtained with gaseous CO2, as previously reported in the literature.
