Notes:
The endo-7-[(dialkylamino)methyl]-3-borabicyclo[3.3.1]nonanes 1 and 2 have been synthesized and their intramolecular complex formation of the corresponding 2-azonia-1-boratatricyclo[4.3.1.14,8]undecanes 3 and 4 has been studied in the gas phase by UV photoelectron spectroscopy and in solution by 11-NMR spectroscopy. Deviations of the characteristic spectral features from those of the monofunctional bicyclic boranes 5 and amines 6 and 7 indicate that in the gas phase the (dimethylamino)boranes with a B-alkyl substituent adopt the tricyclic form 3a-c whereas the diethylamino and the B-methoxy derivatives 1e and 2 prefer the bicyclic structure. In solution some deviations from this behavior are observed.
