  Reactions of 1,2-dihaloethanes with chalcogenide anions

  摘要：

  Reactions of 1,2-dihaloethanes with chalcogenide anions generated from elemental chalcogens and dimethylchalcogens were performed in the hydrazine hydrate-KOH system. The use of anions Se-x(2-) and Te-x(2-) (x = 1-4) resulted in ethylene evolution and chalcogen regeneration (or in increased x value in an anion). Oligomers of Thiokol type formed only in the reaction of the 1,2-dichloroethane with a mixture of potassium disulfide and diselenide. The reductive cleavage of oligomers obtained in the hydrazine hydrate-KOH system followed by methylation led to the formation of 1,2-bis(methylthio)ethane, 1-methylseleno-2-methylthioethane, and 1,2bis(methylseleno)ethane. The features of substitution with chalcogenide anions in vicinal dihalides are discussed. Mass spectra of compounds obtained were measured and analyzed.

  Total NMR band shape fitting methods have provided accurate energy data for inversion barriers at sulphur and selenium in complexes of types cis-[MX2L] (M = PdII, PtII; X = Cl, Br, I; L = MeS(CH2)2SMe, MeS(CH2)3SMe, o-(SMe)2C6H3Me, cis-MeSCH=CHSMe) and [PtXMeMeE(CH2)2E′Me}] (E= E′= S or Se and E = S, E′= Se; X = Cl, Br, I). Barrier energies were found to decrease by 10–12 kJ mol−1 in going from aliphatic

  Mixed chalcogen ligand complexes of trimethylplatinum(IV) halides of general type [PtXMe3(MeSRSeMe)][R =(CH2)2 or o-C6H4] have been prepared and the energy barriers associated with the pyramidal inversions of the individual chalcogen atoms measured by total band-shape dynamic n.m.r. methods. At elevated temperatures an intramolecular scrambling of all of the Pt-methyls occurs, associated with a fluxional
