Organoselenium ligands for heterogeneous and nanocatalytic systems: development and applications

Abstract

Organoselenium ligands have attracted great attention among researchers during the past two decades. Various homogeneous, heterogeneous and nanocatalytic systems have been designed using such ligands. Though reports on selenium ligated...

Molecular Organosulphur, Organoselenium and Organotellurium Complexes as Homogeneous Transition Metal Catalytic Systems for Suzuki Coupling

“…During last two decades, organochalcogen compounds have emerged as a distinguished class of easily synthesizable, air‐/moisture‐insensitive and extremely stable ligands with a long shelf life [10–12] . They have also shown resistance towards oxidation in the order Se>S>Te [114] .…”

“…During this reaction, chemically‐different fragments participate in electronically divergent processes and conjoins with the help of some metal catalyst. For improvement in the performance of this reaction, a large number of catalytic systems have been developed [9–17] . Such systems include preformed complexes of metals with a variety of ligands [10,11,14,15,17] in molecular form (i. e., homogeneous catalysts).…”

“…Moisture‐insensitivity is an extra advantage. In addition to Suzuki coupling, they show catalytic potential for several other chemical transformations [10,11,87–107] too. In the recent past, some of such systems have also been used for its green catalysis in water and room temperature [20,21,27,33,34,44,48,49,50,55,61,63,66,73,74] .…”

Functionalization of graphene oxide with a hybrid P, N ligand for immobilizing and stabilizing economical and non-toxic nanosized CuO: an efficient, robust and reusable catalyst for the C–O coupling reaction inO-arylation of phenol

“…in the head groups according to their applications. 10–15 It is assumed that, during the catalytic process, the role of the donor sites ( i.e. , N/P/O/S/Se/Te) and steric architecture of the ligand is as crucial as in the case of catalysis with homogeneous molecular complexes.…”

Unexpected kinetically controlled organoselenium-based isomaleimide: X-ray structure, hirshfeld surface analysis, 3D energy framework approach, and density functional theory calculation

“…They have also manifested good histone deacetylase inhibitor activity (Adimulam et al, 2021). On the other hand, OSe compounds were extensively used as semiconductors in advanced materials, including photovoltaic cells and sodium-ion batteries and catalysts for the H 2 evolution (Arora et al, 2021). Additionally, the pharmacological properties of OSe naturally occurring and drug molecules are attributed to the presence of the Se atom as a part of their scaffolds.…”
