From <i>In Situ</i> Monitoring to Better Understanding of the Suzuki‐Miyaura Cross Coupling in the Solid State

Abstract Effects of various A dditives, B ase, C atalyst, as well as s ubstrates on the mechanochemically‐induced Suzuki‐Miyaura reaction have been studied. In situ Raman monitoring of the solid‐state reactions gave a detailed view of the reaction course and allowed a direct comparison of the time‐resolved product formation. The acquired knowledge allows in‐depth understanding of the reaction, especially the action of the catalyst in presence of diverse chemicals, leading to the more efficient cross coupling reactions in the solid state.
