✦ Synopsis

The (η 4 -1-azabuta-1,3-diene)tricarbonyliron complexes 10 spectroscopy, as well as X-ray crystallography of 10b, 10c, and 10l. Using variable temperature 13 C-NMR spectroscopy are easily prepared in high yield by condensation of the corresponding arylamines 7 with the cinnamaldehydes 8 and the fluxionality of the complexes 10a, 10b, 10c, 10e, and 2 is investigated and the activation barrier for the turnstile subsequent ultrasound-promoted complexation of the resulting 1-azabuta-1,3-dienes 9 with nonacarbonyldiiron. rotation of the tricarbonyliron fragment is determined. The transfer reaction and the structural factors influencing the The complexes 10 are shown to represent excellent reagents for the transfer of the tricarbonyliron fragment onto transfer of the tricarbonyliron fragment are extensively investigated. cyclohexa-1,3-diene (1a). The structural characterization for the complexes 10 is achieved by IR, 1 H-NMR, and 13 C-NMR
