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.

The copper aminotropones Cu[ON(R′)C7H4R-4] 2 [R = H, R′ = Me (13), Et (14), n-Pr (15), n-Bu (16), Bz (17), MenOCH2CH2 (20); R = i-Pr, R′ = Me (18), n-Pr (19), MenOCH2CH2 (21)] have been prepared from the corresponding aminotropones HN(R′)OC7H4R-4 (1-7) by reacting with copper(II) acetate in aqueous ethanol. 20, 21 contain the flavourant, menthol, as part of the ligand. The structures of 5 (R = H, R′ = Bz), a hydrogen-bonded dimer, 14 and 20, both incorporating square-planar, four-coordinate copper centres, have been determined by X-ray crystallography. The antibacterial activities of complexes 13, 17, 20 and 21 have been assayed against Staphylococcus waneri, an in vitro model of plaque inhibition effects, and found to be more active than a commercial toothpaste formulation, but less active than the O,O-chelated copper(II) complex of ethylmaltol.

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

A synthetic route was developed for preparation of 2-aminotropone oximes 10-14, a new class of compounds, from tropolone 2; 2-methoxytropone imines 7-9 and tropylium salts 17 were generated as the key intermediates.
