Three novel aminotroponiminate (ATI) zinc complexes I-III (I = [(Ph2)ATI]Zn-N(SiMe3)2, II = [(C6H3-2,6-C2H5/Ph)ATI]Zn-N(SiMe3)2, and III = [(C6H

The syntheses and photophysical study of novel fluorescent boron-aminotroponimine complexes are described. The chemical structure of one of the boron complexes was confirmed by single crystal X-ray analysis, which shows the appearance of the distorted tetrahedral geometry at boron. The photophysical studies of these complexes revealed that the boron-aminotroponimines are fluorescent molecules with quantum yields ca. 0.17–0.28.
Intramolecular hydroamination with homogeneous zinc catalysts: Evaluation of substituent effects in N,N′-disubstituted aminotroponiminate zinc complexes

A series of symmetrical and unsymmetrical N,N′-disubstituted aminotroponimines (ATIHs) have been prepared. Substituents ranging from linear to cyclic alkyl groups, chelating ethers, and aryl groups were employed. The corresponding aminotroponiminate zinc
Solid-state structure and tautomerism of 2-aminotroponimines studied by X-ray crystallography and multinuclear NMR spectroscopy

Structural studies in the solid state by X-ray crystallography and by 13C and 15N CPMAS NMR spectroscopy carried out on a series of 2-aminotroponimine derivatives 2-5 has allowed to establish the existence of hydrogen bonding and to determine the most stable tautomer. Almost all the structures reflect the classical double-well potential function for the N-H...N hydrogen bonds. Only in the case of the compound N-(pyrrol-1-yl)-2-(pyrrol-1-ylamino)troponimine (5) the crystal structure shows two independent molecules, one with a classical hydrogen bond and another with either a single-well or a low-barrier hydrogen bond. The structure of this compound is discussed with the use of the solid-state NMR spectroscopic data. 2-Aminotropones, as intermediates to the 2-aminotroponimines, show the oxo-tautomer as the stable form. B3LYP/6-31G* calculations are used to rationalise the experimental results. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
