Energetics of Metal-Ligand Multiple Bonds. Thermochemistry of Tantalum(V) Alkylidene Formation

摘要

These results demonstrate not only that early transition metal alkylidene-forming α-elimination and other processes are driven by the strong metal-alkylidene bonds that are formed but also that the metal-ligand bonding energetics are ideally poised for alkylidene-metallacycle catalytic cycles with minimal en- thalpic excursions.
