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.
