- Abstract
The configurations of a series of mono- and bis-Fe(CO)3 complexes of 12-oxa[4.4.3]-propella-2,4,7,9-tetraene ( 1) and of 11,13-dioxo-12-methyl-12-aza[4.4.3]propella-2,4,7,9-tetraene ( 7) as well as of a trienic aza-propellane complex have been studied in solution by 13C- and 1H-NMR. spectroscopy. Praseodymium-induced 13C-shifts of the metalcarbonyl carbon atoms and of the central carbon atom of the complexed diene systems are particularly sensitive and useful to prove exo- or endo-configuration of the tricarbonyliron ligand. In addition, H,H- and C,H-coupling constants of the complexes and parent compounds are reported and discussed.
