Discuss the structure and stability of Metal alkyl complexes in terms of its kinetic and thermodynamic...
Homework Answers
Transition metal alkyl complexes have stronger Metal-Carbon bond and thus are more stable thermodynamically as compared to corresponding lead alkyls. To stop beta-hydride elimination we can block any available coordination sites by donor ligands by making 18-electron complexes or/and by using alkyl ligands that are stable to beta-hydrogen elimination and do not do reductive elimination.
