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, easy-to-handle catalyst and a stoichiometric amount of glycerol. The reaction features are high yields, based on atom economy, easy performance on gram-scale, metal- and solvent-free conditions as well as applicability to different types of N-heteroarenes.

We have found that fibrous nanosilica (KCC-1) can used as a excellent support for the synthesis of highly sparse nanoparticles. KCC-1 has high surface area that was functionalized with 1,3-bis(dimethylthiocarbamoyloxy)benzene groups acting as the strong performers so that the Pd (II) was complex without aggregation on the fibers of the KCC-1 microspheres (KCC-1/BTB/Pd). For synthesis of 3-sulfenylindoles from aryl iodide, indoles, and thiourea used from the KCC-1/BTB/Pd NPs as a catalyst that showed excellent catalytic activities under green conditions. Compared with the traditional substrate, KCC-1/BTB/Pd substantially increases protection and the accessibility of the nanoparticle sites due to its three dimensional hierarchical structure.

An efficient Cs2CO3-catalyzed oxidative coupling of thiols with phosphonates and arenes that uses molecular oxygen as the oxidant is described. These reactions provide not only a novel alkali metal salt catalyzed aerobic oxidation, but also an efficient approach to thiophosphates and sulfenylarenes, which are ubiquitously found in pharmaceuticals and pesticides. The reaction proceeds under simple and mild reaction conditions, tolerates a wide range of functional groups, and is applicable to the late-stage synthesis and modification of bioactive molecules.
