“…This novel protocol allowed the synthesis of a variety of disele-nides, ditellurides, and disulfides with a very short reaction time (Scheme 33). [53] Various reagents have been used as a source of sulfur for the CÀS coupling reaction with different halides. An efficient synthetic approach to obtain variously substituted thiophenes through a copper-catalyzed tandem S-alkenylation of potassium sulfide with 1,4-diiodo-1,3dienes has been developed (path A, Scheme 34).…”

“…Microwave irradiation technique was introduced by Gedye and coworkers [15] for organic synthesis and later it has been widely used in chemistry to accelerate chemical reactions [16][17][18]. Since microwaves are of long wavelength, the energy penetrates deeper than ultraviolet or electron-beam irradiation [19].…”

“…Isso sugere que a reação possa envolver um processo catalítico heterogêneo, porém, provavelmente possa ocorrer a agregação parcial das nanopartículas, diminuindo assim sua área superficial e, consequentemente, o potencial catalítico. 52 Além disso, outro fator que contribui para a diminuição da atividade catalítica do material recuperado é a adsorção de matéria orgânica após a sua recuperação.…”
