Conclusions

  1. 1.

    In the IR spectrum of solutions of vinylmethyltelluride in n-heptane the doublet form of the valence oscillation band of the double bond is due to rotational isomerism. By analyzing the temperature dependence of the doublet shape, the low-frequency component of the doublet was identified as the s-cis-rotamer.

     
  2. 2.

    The differences in the enthalpies (4.6 ±0.2 kJ/mole) and entropies (-11.1 ±0.3 e.u.) of the vinlymethyltelluride rotamers have been calculated and it has been shown that the p,Πconjugation in its molecule is weaker by a factor of 2 than in vinylmethylsulfide.
