Schumann, H.,Magerstaedt, M.
, p. 147 - 150 (1982)
Tetraorganotin compounds react with tellurium tetrachloride or tellurium tetrabromide with formation of the corresponding organotellurium trihalides and diorganotellurium dihalides. 125Te NMR spectra of the reaction mixtures are used to determine the reac

An efficient and practical synthesis of tellurium tetrachloride from elemental tellurium and sulfuryl chloride is described.
Preparation and characterization of a series of bromodiphenyl(N,N-dialkyldithiocarbamato)tellurium(IV) compounds where R = Me, Et, i-Pr, Bu, and of chlorodiphenyl(N,N-dibutyldithiocarbamato)telluriumm(IV) and diphenylbis(N,N-dibutyldithiocarbamato)tellurium(IV). Crystal structure of P...

The series Ph2TeBr, where R = Bu, Pr, i-Pr, Et, and Me, as well as Ph2TeCl and Ph2Te2, where R = Bu, Pr, have been synthesized and characterized by elemental analysis and vibrational spectroscopy.Comparisons of the effect of changing R groups and halogen atoms can be made based on the two crystal structures determined herein along with earlier work.The geometry about tellurium is consistent with that of a distorted sawhorse structure where the dithiocarbamate groups are monodentate (or anisobidentate).The crystal structures of Ph2TeBr, 4, and Ph2Te2, 7, were completed.The cell parameters for 4 are a = 11.204(3) Angstroem, b = 14.106(11) Angstroem, c = 13.867(10) Angstroem, α = 99.62(6) deg, β = 102.76(5) deg, γ = 87.73(4) deg, V = 2107 Angstroem3, Z = 4, R = 0.0448, and Rw = 0.0489 and for 7 are a = 19.392(6) Angstroem, b = 9.622(2) Angstroem, c = 19.089(6) Angstroem, β = 104.70(2) deg, V = 3445(2) Angstroem3, Z = 4, R = 0.0397, and Rw = 0.0439.Nuclear magnetic resonance spectra are not simple and indicate that several species are present in solution, as rearrangements and reductive elimination take place. Key words: structure, tellurium, bromo, diphenyl, dialkyldithiocarbamato.
