Lima,Ângela M. A.; Paula,Wenderson T. de; Leite,Iris C. H. L.; Gazolla,Poliana A. R.; Abreu,Lucas M. de; Fonseca,Victor R.; Romão,WandersonEugenol (C10H12O2, 4-allyl-2-methoxyphenol) is a phenolic natural product that has several biological activities and possibilities of applications. It is herein described the synthesis of eugenol-fluorinated triazole derivatives and evaluation of their fungicidal activity. The reaction of eugenol with epichlorohydrin resulted in the preparation of (±)-2-((4-allyl-2-methoxyphenoxy)methyl)oxirane (1) in 88% yield...
Synthesis, Characterization, and Application of Europium(III) Complexes as Lumi...
Macrino,Clebson J.; Silva,Elias M.; Cunha,Victor R.; Fonseca,Victor R.; Cunha Neto,Álvaro; Araújo,Joyce R.; Lacerda Jr.,Valdemar; Romão,WandersonIn this work, three complexes were synthesized from the trivalent europium ion (EuIII), using the picrate anion (pic), and delta-valerolactam (DVL), epsilon-caprolactam (EPK), and oenantholactam (OEN). The synthesized complexes [Eu(pic)3·(DVL)3], [Eu(pic)3·(EPK)3], and [Eu(pic)3·(OEN)3] were studied as luminescent markers for application as security elements in Brazilian banknotes. All complexes showed red colo...
