N-heterocyclic carbenes (NHCs) can be easily modified by introducing functional groups at the nitrogen atoms, which leads to versatile coordination chemistry as well as diverse catalytic applications of the resulting complexes. This article summarizes our contributions to the field of NHCs bearing different types of sulfur functions, i.e., thioether, sulfoxide, thiophene, and thiolato. The expe...

Abstract A Pd-Co bimetallic alloy encapsulated in melamine-based dendrimer supported on magnetic nanoparticles denoted as ?-Fe 2 O 3 @MBD/Pd-Co was synthesized by a facile co-complexation-reduction method and characterized sufficiently. The catalytic evaluation of showed promising results the Mizoroki–Heck Buchwald–Hartwig amination reactions various iodo-, bromo- challenging chloroarenes aqueo...

In recent years, the immobilization of palladium nanoparticles on solid supports to prepare active and stable catalytic systems has been deeply investigated. Compared inorganic materials, naturally occurring organic solids are inexpensive, available abundant. Moreover, surface these is fully covered by chelating groups which can stabilize metal nanoparticles. present review, we have focused our...

Cyclometallated compounds have been extensively studied, in particular those with palladium and platinum. This is because of their possible applications medicinal chemistry, as anticancer or antimicrobial agents; some cases, similar results cisplatin, carboplatin oxaliplatin. What also remarkable use homogeneous catalysts, for example, cross coupling reactions such Suzuki–Miyaura Mizoroki–Heck....

Abstract

Achieving high selectivity in the Heck reaction of electronically unbiased alkenes has been a longstanding challenge. Using a nickel-catalyzed cationic Heck reaction, we were able to achieve excellent selectivity for branched products (≥19:1 in all cases) over a wide range of aryl electrophiles and aliphatic olefins. A bidentate ligand with a suitable bite angle and steric profile was key to ob...
