Exploring the Scope of a Novel Ligand Class: Synthesis and Catalytic Examination of Metal Complexes with ‘Normal’ 1,2,3-Triazolylidene Ligands

Using new ‘normal’-substituted 1,2,3-triazolylidene silver compounds as starting materials allowed for preparation of a series of molybdenum, ruthenium, rhodium, and palladium transition metal complexes bound to the new 1,2,3-triazolylidene ligand system. In this work, the first triazolylidene Mo compound is presented as well as the first structural investigation of a silver complex with a monodentate 1,2,3-triazolylidene. Furthermore, the triazolylidene Pd complex and the Mo complex were tested as precatalysts in Suzuki–Miyaura coupling and epoxidation catalysis, respectively.
