Resumo

GHOLAMZADEH, PARISA; ZIARANI, GHODSI MOHAMMADI  e  BADIEI, ALIREZA. APPLICATION of SBA-Pr-SO3H IN THE GREEN SYNTHESIS OF ISATINHYDRAZONE DERIVATIVES: CHARACTERIZATION, UV-Vis INVESTIGATION AND COMPUTATIONAL STUDIES. J. Chil. Chem. Soc. [online]. 2016, vol.61, n.2, pp.2935-2939. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072016000200017.

An efficient and green synthesis is developed for the preparation of the arylidene isatinhydrazone derivatives 4a-m using a heterogeneous mesoporous acid catalyst of SBA-Pr-SO3H with a pore size of 6 nm under solvent free conditions. The hydrazones 4a-m were then analyzed by UV-Vis spectroscopy and the results were used for the calculation of the HOMO-LUMO band gap. In addition, the quantum chemical calculations were performed to provide an illustrative explanation for the obtained band gap; it is found that probably these molecules have a high tendency to donate electrons to the appropriate small-molecule acceptors with low energy and empty molecular orbital.

Palavras-chave : Arylidene isatinhydrazone; SBA-Pr-SO3H; Green synthesis; HOMO-LUMO band gap; Small-molecule acceptors.
