A nuclear magnetic resonance study of sulphur and selenium inversion in complexes of trimethylplatinum(IV) halides with dithio- and diselenoethers
Abstract
Dynamic n.m.r studies have yielded accurate energy data for S and Se pyramidal inversion in complexes of type [PtXMe3(L–L)][X = Cl, Br, or I; L–L = MeE(CH2)nEMe, E = S or Se, n= 2 or 3]. The mechanism of the inversion process and the effects of atomic mass, ring size, and nature of halogen on the barrier energies are discussed.
