We report the application of two new phenyl-tetrazolylidene carbenes as ligands in tetrazolylidene-cyclopentadienone ruthenium(0) complexes with non-mesoionic and mesoionic substitutions. The complexes were synthesized in good yield and fully characterized; X-ray structure determination confirmed the binding mode of the ligand in complex 2. Reactivity studies were performed to investigate the effect of phenyl substituent position in the heterocyclic ligand on the behavior and stability of the complexes.
Here we present two new phenyl-tetrazolylidene carbenes as ligands in non-mesoionic (1,4-substitution pattern) and mesoionic (1,3-substitution pattern) tetrazolylidene-cyclopentadienone ruthenium(0) complexes namely 1 and 2 respectively. The complexes have been obtained in good yield and fully characterized; X-ray structure determination confirmed the binding mode of the ligand for 2. Reactivity studies has been performed in order to shed light on the fact that the phenyl substituent position in the heterocyclic ligand can seriously change complexes behavior and stability.
