, p. 176 - 179 (2016)
A method for the simple, efficient, and atom-economic amidoselenenylation of simple alkenes under mild conditions using TiCl4 as a catalyst and N-(phenylseleno)phthalimide as both a nitrogen and selenium source was developed. A broad range of olefins can be applied to afford vicinal amidoselenides in good yield and with high regioselectivity and diastereoselectivity.

An efficient protocol for the construction of valuable β-hydroxy aryl selenides from easily available arylamines, elemental selenium, and epoxides through a transition-metal-free radical process is described. A wide variety of β-hydroxy aryl selenides were obtained in good to excellent yields with excellent stereo- and regioselectivity. In this reaction, two C-Se bonds can be built along with the cleavage of a C-N and C-O bond, demonstrating the high step economy and efficiency of this approach.
Visible-light-induced oxidative coupling of vinylarenes with diselenides leading to α-aryl and α-alkyl selenomethyl ketones

A visible-light-induced oxidative coupling of diselenides with readily available vinylarenes is demonstrated. This benign protocol allows one to access a wide range of α-aryl and α-alkyl selenomethyl ketones in good yields with excellent functional group compatibility. The distinct advantages of this protocol over all previous methods include the use of a green solvent and air as an oxidant and the lack of a photocatalyst, a base, and an oxidant as well as better green chemistry matrices. Furthermore, the title reaction can be performed with natural sunlight, the most sustainable energy source imaginable. Additionally, the mild reaction conditions, easy operation and suitability for the modification of styrene-functionalized biomolecules make the current reaction system a more attractive method for the synthesis of a variety of medicinal and agrochemical compounds of interest.
O-(tert-butyl) Se-phenyl selenocarbonate: A convenient, bench-stable and metal-free precursor of benzeneselenol
Temperini, Andrea,Siciliano, Carlo
, (2020/06/17)
A study by our laboratory shows that air, light and moisture stable O-(tert-butyl) Se-phenyl selenocarbonate could be employed as a safer, practical and efficient alternative to generate “in situ” benzeneselenol or benzeneselenolate anion under different and transition metal-free conditions. This procedure seems to be of general application since the nucleophilic selenium species obtained can be trapped by electrophiles such as alkyl halides, epoxides and electron-deficient alkenes and alkynes under different reaction conditions.
