Factors that Affect the Rates of Reductive Elimination

Factors that Affect the Rates of Reductive Elimination 

Many factors control the rates of reductive elimination reactions (Equation 8.4). In many cases, the effects of the steric and electronic properties of the metal complex on the rate of reductive elimination are the opposite of the effects of these properties on the rate of oxidative addition because the effects originate from thermodynamic factors. The steric and electronic properties of the metal ttiat thermodynamically favor oxidative addition must thermodynamically disfavor the opposite reductive elimination reaction. 

For M First row complexes react faster than second row 

For L More sterically hindered complexes react faster than less sterically hindered complexes. 

For n complexes in which n = 1 or 3 react faster than complexes in which n = 2 or 4.
