摘要
Reaction of [RuCl(Pr-i-pymox)(eta(6)-mes)](+) 1b [Pr-i-pymox = 4-isopropyl-2-(2-pyridyl)-1,3-oxazoline, mes = 1,3,5-trimethylbenzene] with AgSbF6 then with halide gives [RuX(Pr-i-pymox)(eta(6)-mes)](+) (X = Cl 1, Br 2, I 3), each as a mixture of diastereomers, the kinetic product being formed preferentially with net inversion of configuration at the metal; the structures of 2a and 2b have been determined by X-ray crystallography.
