Abstract
Several cyclobutabenzenetricarbonylchromium(0) complexes have been prepared by reaction of substituted cyclobutabenzenes with triammintricarbonylchromium(0) (13), and characterized by 1H NMR, 13C NMR, IR, and mass spectroscopy. Diastereomer ratios were determined by 1H NMR, and signal assignments were verified by a NOE experiment. HPLC separation of diastereometric products was carried out in one representative case. A photochemical carbonyl ligand exchange took place in 70% yield with triphenylphosphane. Deprotonation of cyclobutabenzenetricarbonylchromium(0) (2) with n-BuLi/tmeda was observed only for the aromatic protons, not the benzylic ones.
