Organotellurium ligand-facilitated metal structures are known for their catalytic activity, anti-cancer activities, and nanomaterial applications. A wide range of organotellurium ligands, including telluroethers, pincer-based frameworks, tellurolates, have been extensively explored coordination with diverse centers. These ligands successfully complexed base metals, platinum group rare earth elements, representative providing a unified resource literature on complexes ligands. The resulting metal-organotellurium exhibit intriguing structural diversities potential applications in catalysis, materials science, chemistry. comprehensive review various has not available since 2005. Moreover, within the broader field chalcogen chemistry, remain relatively less explored. Hence, this focuses synthetic strategies containing addressing significant critical gap existing literature. This provides analysis focusing synthesis, diversity, Beyond fundamental significance, these play vital role life sciences, nanochemistry, science. Their proficiency is evident essential organic reactions, Suzuki-Miyaura Mizoroki-Heck couplings, alcohol oxidation, C-N bond formation, aldehyde activation, nitrophenol reduction.

Abstract Herein, we have reported a new series of NNS‐donor ligands coordinated Ni(II) complexes and utilized them as catalytic activator to synthesize N ‐alkylated amines 1,2‐disubstituted benzimidazoles. The reaction thiophenol/4‐chlorothiophenol/4‐methylthiophenol/4‐methoxythiophenol with 2‐bromo‐ ‐quinolin‐8‐yl‐acetamide in presence sodium hydroxide ethanol at 80 °C gave [C 9 H 6 N‐NH−C(O)−CH 2 ‐S−Ar] [Ar=C 5 ( L1 ); C 4 Cl‐4 (L2 Me‐4 (L3 ) ‐OMe‐4 (L4 )], respectively. corresponding ‐ L4 Ni(OAc) methanol for 3 hours resulted octahedral nickel [( ‐H) Ni] C1 ), L2 C2 L3 C3 C4 All compounds been characterized by micro spectroscopic analysis. molecular structure – has also determined single crystal X‐ray diffraction data. utility were evaluated the ‐alkylation aniline benzyl alcohols, benzimidazoles synthesis. obtained results indicate that complex showed better activity both alcohols [catalyst loading: 2.0 mol %; Yield up 92 %], derivatives 94 %)]. mechanistic studies suggested works through hydrogen borrowing from alcohol its subsequent utilization situ reduction imine. experimentally observed reactivity patterns found good agreement HOMO‐LUMO energy gaps DFT analysis complexes.
