Abstract

Kinetics of substitution reactions of trans-[Ru(teta)Cl₂]⁺ by bromide and of trans-[Ru(L)Br₂]⁺ (L = teta or tetb) by chloride have been studied over a range of temperatures. The observed steric acceleration of k₁(teb) > k₁(teta) > k₁(cyclam) for the release of the first coordinated halide from analogous dihalogen complexes supports a dissociative mechanism for these reactions. A similar trend of steric acceleration has also been found to support the S_N1cB mechanism for the base hydrolysis of trans-[Ru(L)ACl]⁺ (L = tetb, teta, or cyclam; A = Cl or OH). © 1983 American Chemical Society.
