Abstract
In this study, a mechanochemical adaptation of the McMurry coupling reaction was developed to synthesize ethylenes using Zn/TiCl4/Et3N as reagents. Leveraging solvent-free ball-milling conditions, the method achieved up to 97% yield across >23 substrates. The reaction was performed without inert gas protection in a Teflon milling jar and was found to be scalable and to accommodate various functional groups.
