Periodic Trends and Fluxionality Effects on Transition Metal Catalyzed Sulfoxidation.

ABSTRACT: Despite the extended interest in d⁰ metal complexes as catalysts for peroxide activation and eventual oxygen transfer processes, there are still gaps in the understanding of how they proceed at the microscopic level. Herein, we have considered sulfide oxidation with cumyl hydroperoxide as a test system, performing the reaction with a series of eight different aminotriphenolate d⁰ metal complexes: Ti(IV), Zr(IV), Hf(IV), V(V), Nb(V), Ta(V), Mo(VI), and W(VI). The reactivity and selectivity of the catalytic systems, as well as the effect of a strong Lewis base (dimethylhexyl-N-oxide), have been determined experimentally, correlating kinetic values with Sanderson electronegativity values. Theoretical calculations of the catalytic cycles have been performed to have
