Thermal studies on Ni(II), Cu(II) and Pd(II) complexes of 6-amino-5-formyluracil and its N-methyl derivatives

Journal of Thermal Analysis and Calorimetry
Volume/Issue:
Volume 32: Issue 4
DOI:
https://doi.org/10.1007/bf01905167
Authors: L. E. Garcia-Megias, E. Colacio-Rodriguez, A. Garcia-Rodriguez, J. Ruiz-Sanchez, and J. M. Salas-Peregrin

The thermal behaviour of 6-amino-5-formyluracil (HFU), 6-amino-1-methyl-5-formyluracil (1-MFU), 6-amino-3-methyl-5-formyluracil (3-HFU) and 6-amino-1,3-dimethyl-5-formyluracil (HDFU) is described. Only HDFU is shown to contain crystallization water. Dehydration and fusion enthalpy values have been calculated from the DSC curves. Likewise, the thermal behaviour of new complexes obtained by reaction between the above pyrimidine derivatives and Ni(II), Cu(II) and Pd(II) ions is reported.

Thermal and spectral studies on some tetrachloroaurates of 8-alkyltheophylline derivatives

Journal of Thermal Analysis and Calorimetry
Volume/Issue:
Volume 30: Issue 4
DOI:
https://doi.org/10.1007/bf01913305
Authors: E. Colacio-Rodriguez, M. N. Moreno-Carretero, and J. M. Salas-Peregrin

Tetrachloroaurates of 8-ethyl-, 8-isopropyl-, 8-propyl- and 8-pentyltheophylline were synthesized and studied by1H-NMR, TG and DSC techniques. The metal is not coordinated to the 8-alkyltheophylline derivatives and forms a salt-like structure.
