摘要：

The crystal structure and FUR spectrum of 3-formylchromone (0) have been analysed. A new organic ligands, 3-(anilinomethylene)-2-methoxychroman-4-one (1) and 3-(1',4'-benzodioxan-6'-aminomethylene)-2-methoxychroman-4-one (2) were synthesized. The products of reactions between 3-formylchromone and aniline and 6-amino-1,4,-benzodioxane were studied by elemental analysis, FTIR spectroscopy, thermal analysis and X-ray crystallography. It has been found that these reactions allow to obtain derivatives of 4-chromanones from 3-formylchromone by the mechanism of nucleophilic addition, accompanied by the opening of the pyrone ring. The experimental results indicate that compounds (1) and (2) are thermal stable up to 90 and 100 degrees C, respectively. The FTIR spectra and X-ray analysis showed the present of methoxy-group in these compounds. (c) 2010 Elsevier B.V. All rights reserved.
