Resumen

SOUZA, ANA O. DE et al. PHYSICO-CHEMICAL CHARACTERIZATION OF THE INCLUSION COMPLEX BETWEEN A 2-PROPEN-1-AMINE DERIVATIVE AND b-CYCLODEXTRIN. J. Chil. Chem. Soc. [online]. 2005, vol.50, n.3, pp.591-596. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072005000300012.

Inclusion complexes and physical mixtures were prepared with isomeric mixture of E/Z (50:50) of 3-(4'-bromo-[1,1'-biphenyl]-4-yl)-3-(4-bromophenyl)-N,N-dimethyl-2-propen-1-amine (BBAP) and b-cyclodextrin (b-CD) in different proportions. In this study, theoretical calculations using Molecular Mechanics MM+ force field were applied to predict the structures of the inclusion complexes formed by interaction of BBAP and b-cyclodextrin. Circular dichroism, differential thermal analysis (DTA), X-ray diffraction and 13C CP/MAS NMR methods were used to characterize the inclusion complexes and provide information about the stoichiometry of the inclusion complexes. The combined spectroscopy techniques indicate the formation of a complex of BBAP/b-CD in the molar proportion of 1:1 and 1:2 by co-evaporation and no complexation was detected in the physical mixture of the compounds

Palabras clave : b-cyclodextrin; inclusion complexes; 2-propen-1-amine.
