Molecular dynamics of sterically hindered dihalo- and diacyloxydiaryltelluranes
摘要:
Dihalo- and diacyloxydi(2,6-dimethylphenyl)telluranes [10-Te-C2X2; X = halogen and RCO(2)] were prepared and variable-temperature H-1 NMR studies revealed that these telluranes were composed of the sterically congested rotamers. The first examples of the activation parameters for rotation of the Te-C bonds were obtained in D NMR experiments.
