Oxovanadium complexes display unprecedented selectivity as catalysts for aerobic C-H, C-O and C-C bond cleavage in lignin models that can be controlled by choice of ancillary ligands and reaction solvent.1-3 In this talk we present new examples of selective oxovanadium catalysts using ancillary ligands with hemilabile nitrogen bases. Disparate reaction pathways are probed using isotopic labeling and DFT computational chemistry. 1. Son, S.; Toste, F. D. Angew. Chem. Int. Ed. 2010, 49, 3791-3794. 2. Hanson, S. K.; Baker, R.
