in solution. The crystal structures of all compounds but 3 have been determined and confirm that all form dimers with six-membered M2C2N2 rings in the chair conformation. The mass spectra indicate that the dimers are retained in the gas phase, and for 1 the molecular dynamics of ring inversion was monitored in solution by variable-temperature NMR spectroscopy, showing that the barrier for the inversion
Aromatics are acylated by the Friedel-Crafts method by carrying out the acylation in the presence of metalalkyls or metalalkyl halides of metals or semimetals of main groups two to five and/or of metals of subgroups two or four of the Periodic Table.
