• Resumen

  • The synthesis Of (eta5-C5H5)2TiS5 and the subsequent variable-temperature 1H NMR spectroscopy in d8-toluene form the basis for an integrated laboratory experiment combining inorganic and physical chemistry. The synthesis illustrates Schlenk techniques and use of a vacuum line, while the variable-temperature NMR spectroscopy follows the kinetics of the chair-to-chair inversion of the TiS5 ring.
