It is well-known that acyl-thioureas and acylthiocarbamatehe belongions have bioactive properties; in addition, the presence of several functional groups in these compounds' molecules allows them to behave as polidentate systems giving rise to interesting chemical and chemical-physical properties.

The scientific importance of this work lies in having synthesized and characterized three series of polidentate compounds that include 15 acyl-thioureas, 29 acylthiocarbamates, 13 of which are new, and 8 new methylimidothiocarbamates.

It was used in the synthesis the radiation technique with microwaves, and there were carried out theoretical studies using semi-empirical calculations on the reactivity of the polidentate systems approached.

12 articles have been published, 8 of them in internationally prestigious magazines.

The results have been presented in 35 congresses, 6 of them abroad.

7 master's degree theses and 9 dissertations have been defended.
