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 SN1cB mechanism for the base hydrolysis of trans-[Ru(L)ACl]+ (L = tetb, teta, or cyclam; A = Cl or OH). © 1983 American Chemical Society.
