Herein, we describe a simple and efficient route to access aniline-derived diselenides and evaluate their antioxidant/GPx-mimetic properties. The diselenides were obtained in good yields via ipso-substitution/reduction from the readily available 2-ni

A peroxide-mediated protocol for the synthesis of 2-substituted benzothiazoles was developed, starting from bis(o-aminophenyl) disulfides and primary alcohols. Eleven differently 2-substituted benzothiazoles were prepared in moderate to excellent yie

We established a new synthetic methodology for the regioselective β-hydroxyselenilation of olefins employing benzeneseleninic acid and promoted by blue LED light, as alternative energy source. Using a novel perspective, the bezeneseleninic acid emer

We developed a promising synthetic methodology for the regioselective photocatalyzed 3-selenocyanation of indoles, employing potassium selenocyanate (KSeCN) and a blue LED light. The 3-selanylindoles have been emerging as a potentially bioactive clas

Herein, we described the NH4I-catalyzed C H bond chalcogenation of N-heteroaryls in the presence of a minimum amount of DMSO/H2O/acetic acid as additives (2.5/2.5/1 M equiv., respectively), under metal-free conditions. Under optimized conditions, a w

Herein, we report 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, eas

We describe herein a simple, fast and inexpensive protocol for the oxidative coupling of thiols employing a stoichiometric amount of DMSO and iodine as the catalyst. Various aromatic disulfides were obtained in good to excellent yields in short react

We describe herein a microwave-assisted synthesis of β-chalcogen amides through the regioselective ring-opening reaction of 2-oxazolines promoted by bis(organoylchalcogeno)iodo indium(III) in situ generated. This protocol allows the preparation of s
