N-heterocyclic carbenes are widely exploited as ligands in transition metal catalysis, but are largely limited to N-arylimidazolylidenes. Here, the authors report on the steric and electronic properties of thiazol-2-ylidenes, demonstrating that their

Silver–NHC (NHC = N-heterocyclic carbene) complexes play a special role in the field of transition-metal complexes due to (1) their prominent biological activity, and (2) their critical role as transfer reagents for the synthesis of metal-NHC compl

Summary: The biaryl motif is a building block in many drugs, agrochemicals, and materials, and as such it is highly desirable as a synthesis target. The state-of-the-art process for biaryl synthesis from ubiquitous carboxylic acids is decarboxylative

Summary: The development of more reactive, general, easily accessible, and readily available Pd(II)–NHC precatalysts remains a key challenge in homogeneous catalysis. In this study, we establish air-stable NHC–Pd(II) chloro-dimers, [Pd(NHC)(μ-Cl

Transamidation reactions usually require transition metal catalysts and/or harsh conditions. Here, the authors show a general and operationally-simple protocol for the transamidation of amides and amidation of esters by highly selective acyl cleavage
