Abstract

Gutmann donor (DN) and acceptor numbers (AN) were correlated with the effectiveness of liquid assisted grinding (LAG) agents in facilitating the production of palladacycle pre-catalysts including Najera Catalyst II, which was mechanosythesized for the first time. Kinetic analysis was completed for the effects of LAG agent selection on rate parameters in the preparation of a 2-aminobiphenyl palladacycle pre-catalyst. While no single LAG agent was the best for all reactions, LAG agents like methanol, ethanol, and formamide with high AN and mid-range DN values were found to be the most effective, significantly increasing yields and reducing reaction times.
