    The crystal structure of 2-[N,N-dimethylamino)methyl] benzenetellurenyl chloride2004In: Phosphorus, Sulfur, and Silicon, ISSN 1042-6507, Vol. 179, p. 285-292Article in journal (Refereed)
    Abstract [en]

    The crystal structure of 2-[(N,N-dimethylamino)methyl]benzenetellurenyl chloride (2), a compound previously formulated as bis [[2-(N,N-dimethylamino)methyl]phenyl] ditelluride bis hydrochloride (1a), was determinded. In the molecule 2, tellurium is bonded to the carbon of the phenyl group [2.120(3)Å], the nitrogen o fthe ortho dimethylamino substituent [2.362(3)Å], and the chlorine atom [2.536[1]Å]. There also is an intermolecular interaction of the tellurium atom with the phenyl ring of a neighbouring molecule [3.655(1)Å], resulting in the formation of zigzag chains along the b axis. The noncentorsymmetric space group of the crystal can be explained by the chiral surrounding of tellurium.

    Microwave-Assisted Group-Transfer Cyclization of Organotellurium Compounds2004In: The Journal of Organic Chemistry, Vol. 69, no 15, p. 5143-5146Article in journal (Refereed)
    Abstract [en]

    Primary- and secondary-alkyl aryl tellurides, prepared by arenetellurolate ring-opening of epoxides/O-allylation, were, found to undergo rapid (3-10 min) group-transfer cyclization to afford tetrahydrofuran derivatives in 60-74% yield when heated in a microwave cavity at 250C in ethylene glycol or at 180C in water. To go to completion, similar transformations had previously required extended photolysis in refluxing benzene containing a substantial amount of hexabutylditin. The only drawback of the microwave-assisted process was the loss in diastereoselectivity wich is a consequence of the higher reaction temperature. Substitution in the Te-aryl moiety of the secondary-alkyl aryl tellurides (4-OMe, 4-H, 4-CF3) did not affect the outcome of the group-transfer reaction in ethylene glycol. However, at lower temperature, using water as a solvent, the CF3 derivative failed to react. The microwave-assisted grouptransfer cyclization was extended to benzylic but not to primary- and secondary-alkyl phenyl selenides.
