Abstract
The synthesis, spectroscopic characterization, and the X-ray crystal structure determination of tricarbonyl-η6-[1,2-bis(ethylendioxy)cyclobutabenzene]chromium(0) are described. The free enthalpy of activation of the Cr(CO)3 rotation has been determined by variable temperature solid state 13C CP-MAS NMR spectroscopy to be ca. 60kJ/mol.
