Summary: Mechanochemical synthesis using transition-metal catalysts has advantages such as low solvent waste and short reaction times. However, the direct use of transition-metal catalysts in mechanochemical reactions without modifications limits the development of efficient cross-coupling processes. This study presents a new approach, using mechanochemistry-directed design to develop ligands for Suzuki-Miyaura cross-coupling reactions. The embedding of the ligand into a poly(ethylene glycol) polymer prevents catalyst deactivation and shows high catalytic activity at room temperature.

Summary: In this paper, a group of copper-based ternary deep eutectic solvents (Cu-DESs) were synthesized and applied in Glaser-type homo- and cross-coupling of terminal alkynes. These reactions occurred under exogenous-ligand-free, base-free, and additive-free conditions, providing satisfactory to excellent yields (up to 99%) under mild conditions. The Cu-DESs can be recycled eight times, with water being the only by-product, complying fully with the principles of green chemistry.

Summary: Palladium has been widely used in the Suzuki-Miyaura cross coupling reaction for over 30 years, but it comes with drawbacks such as high cost, tedious work-ups, product contamination, and metal leaching. In recent years, other metals like Ni, Cu, Co, Fe, Rh, and Ru have attracted attention for their potential in SMCR, allowing for the synthesis of industrially important compounds with various functional groups. This review discusses recent advancements in catalysis related to SMCR, providing valuable insights for researchers in designing synthetic protocols for pharmacophores and drug molecules.
