Zhang, Jin;Zhang, Pei;Shao, Lei;Wang, Ruihong;Ma, Yangmin;Szostak, Michal research published 《 Mechanochemical Solvent-Free Suzuki-Miyaura Cross-Coupling of Amides via Highly Chemoselective N-C Cleavage》, the research content is summarized as follows. The first mechanochem. strategy for highly chemoselective, solvent-free palladium-catalyzed cross-coupling of amides by N-C bond activation was reported. The method was conducted in the absence of external heating, for short reaction time and shows excellent chemoselectivity for σ N-C bond activation. The reaction showed excellent functional group tolerance and could be applied to late-stage functionalization of complex APIs and sequential orthogonal cross-couplings exploiting double solventless solid-state methods. The results extend mechanochem. reaction environments to advance the chem. repertoire of N-C bond interconversions to solid-state environmentally friendly mechanochem. methods.
