Direct, Metal-free C(sp2 )-H Chalcogenation of Indoles and Imidazopyridines with Dichalcogenides Catalysed by KIO3.
Jamal Rafique,Sumbal Saba,Marcelo S. Franco,Luana Bettanin,Alex R. Schneider,Lais T. Silva,Antonio L. Braga +6 more
TL;DR: A greener protocol for the synthesis of 3-Se/S-indoles and imidazo[1,2-a]pyridines through direct C(sp2 )-H bond chalcogenation of heteroarenes with half molar equivalents of different dichalCogenides, using KIO3 as a non-toxic, easy-to-handle catalyst and a stoichiometric amount of glycerol.
Journal ArticleDOI
Microwave-assisted one-pot synthesis of symmetrical diselenides, ditellurides and disulfides from organoyl iodides and elemental chalcogen catalyzed by CuO nanoparticles
Giancarlo V. Botteselle,Marcelo Godoi,Fábio Z. Galetto,Luana Bettanin,Devender Singh,Oscar E. D. Rodrigues,Antonio L. Braga +6 more
TL;DR: In this article, CuO nanoparticles were applied as a catalyst for C Se, C Te, and C S bond formation in a very short reaction time, which allowed the synthesis of diselenides, ditellurides and disulfides.
Journal ArticleDOI
NH4I-catalyzed chalcogen(S/Se)-functionalization of 5-membered N-heteroaryls under metal-free conditions
Luana Bettanin,Sumbal Saba,Carlos V. Doerner,Marcelo S. Franco,Marcelo Godoi,Jamal Rafique,Antonio L. Braga +6 more
TL;DR: In this paper, the NH4I-catalyzed C H bond chalcogenation of N-heteroaryls in the presence of a minimum amount of DMSO/H2O/acetic acid as additives was described.
Journal ArticleDOI
Solvent- and metal-free selective oxidation of thiols to disulfides using I2/DMSO catalytic system
Luana Bettanin,Sumbal Saba,Sumbal Saba,Fábio Z. Galetto,Gustavo A. Mike,Jamal Rafique,Antonio L. Braga +6 more
TL;DR: A simple, fast and inexpensive protocol for the oxidative coupling of thiols employing a stoichiometric amount of DMSO and iodine as the catalyst and various aromatic disulfides were obtained in good to excellent yields.
Journal ArticleDOI
Green synthesis of 1,3-diynes from terminal acetylenes under solvent-free conditions
TL;DR: In this article, the microwave assisted synthesis of 1,3-diynes from terminal acetylenes, catalyzed by CuI and tetramethylethylenediamine, in the presence of air as the oxidant, at 100 °C for only 10 min under solvent-free conditions.
