Organoselenium chemistry-based polymer synthesis

Abstract

Selenium-containing polymers have become one of the researches focuses of polymer materials in recent years, because of their unique properties. Firstly, selenium can transform among various states of selenoxide, selenone,...

Selenium‐NMR Spectroscopy in Organic Synthesis: From Structural Characterization Toward New Investigations

“…Selenium element has proven to be a suitable nuclide in NMR spectroscopy in studies on stability, [40] reactivity, [41,42] chirality, [43,44,45,46,47,48] polymers, [49,50,51] coordination chemistry, [52,53,54,55] and bio-based experiments. [56,57,58,59] The great potential of 77 Se NMR experiments can be attributed to selenium-77 isotope properties, as spin ( 1 = 2 ), natural abundance (7.63%), no quadrupolar moment, magnetogyric ratio (5.12 × 10 7 rad.s À 1 .T À 1 ) and negligible nuclear Overhauser effect (nOe).…”

Metal-free nucleophilic trifluoromethylselenolation via an iodide-mediated umpolung reactivity of trifluoromethylselenotoluenesulfonate

“…Despite, the negative reputation of selenium due to its toxicity at high doses, it is an essential trace element for human physiology and biochemistry [17][18][19][20]. Furthermore, selenolated compounds found valuable applications in materials [21][22][23], life sciences [19,20,[24][25][26][27][28][29], and drug design [30][31][32][33]. Consequently, the merging of fluorinated moieties, such as CF 3 with selenium could constitute an interesting motif in the design of new molecules, in particular in medicinal chemistry or agrochemistry.…”

Environmentally Compatible Access to α‐Trifluoromethylseleno‐Enones

“…[14] In particular merging of chalcogens and trifluoromethyl group has recently known a growing interest, [15][16][17][18][19][20][21] particularly because of the increased lipophilicity brought by such substituents to the molecules. [22,23] Despite its negative reputation, selenium is an important element either for human physiology [24] or in the design of new compounds for various applications from materials [25,26] to life sciences [27][28][29][30][31][32][33][34][35][36] and drug design. [37][38][39][40][41][42][43] Consequently, the design of CF 3 Semolecules constitutes an interesting strategy for the development of new innovative substrates.…”
