The mononuclear six-membered ring complexes [(PtXme3)(MeSCH2SCH2SME)] X Cl, Br and I) have been synthesised and studied by dynamic NMR methods. The separate energy barriers associated with the pyramidal inversion of the sulphur atoms, platinum-methyl scrambling and chelate ligand rotation were measured by complete band-shape analyses.

Methods of synthesis of compounds MeY(CH2Y)(n) Me (Y=S, Se, Te; n = 1-3) containing several identical or different chalcogen atoms are suggested. The methods are based on the reactions of dichloromethane with elemental chalcogens (Y2-) and dimethyl dichalcogenides (MeY-) activated in the system hydrazine hydrate-alkali. The effect of the chalcogen on the reactivity toward dichloromethane is qualitatively assessed. With elemental tellurium in the system hydrazine hydrate-alkali, reduction of one chlorine atom in dichloromethane and formation of methyltellanyl derivatives are observed.
