In the present review, we discuss recent progress in the field of C–Z bond formation
reactions (Z= S, Se, Te) catalyzed by transition metals. Two complementary methodologies …

Cu-catalysed arylation reactions devoted to the formation of C–C and C–heteroatom bonds
(Ullmann-type couplings) have acquired great importance in the last decade. This review …

A new approach to C− S couplings is reported that relies on nickel catalysis under mild
conditions, enabled by micellar catalysis in recyclable water as the reaction medium. The …

Organochalcogen compounds (containing S, Se and Te) are interesting either for use as an
intermediate in the synthesis of complex molecules or for the exploitation of their biological …

Considering a complete life cycle of metal catalysts, metals are usually mined from ores as
salts (MX′ n), industrially processed to the bulk metal (M) and then converted into the salts …

Transition-metal catalysed cross-coupling reactions are still dominated by palladium
chemistry. Within the recent past, copper has gained ground against palladium by virtue of …

A convenient metal-free and solvent-free iodine-catalyzed regioselective greener protocol to
access different types of unsymmetrical chalcogenides with nitrogen-or oxygen-containing …

Surface functionalization of SBA-15 followed by its reaction with Cu (OAc) 2 has been
carried out to develop a new Cu-grafted functionalized mesoporous material, which …

The C–S cross-coupling reaction of aryl halides with thiols or sulfur sources is a key and
valuable synthetic transformation in chemistry and medicine as well as in biology, and the …

In this paper, we report the synthesis of amine modified SiNPs (silica nanoparticles) by a sol–
gel method and the role of synthesized SiO2 as a solid support for the nanocatalyst CuNPs …
