Solvent-induced dichotomy in the oxidation mechanism of alkyl aromatic selenoethers

Changing solvent polarity (considered in terms of dielectric permittivity ? is an easy experimental way for tuning the reactivity of electrogenerated cation radicals of alkyl aromatic selenoethers. First-order cleavage of SeC3 bond is favored in polar media, whereas bimolecular cation radical disproportionation becomes the main reaction in low-polar solvents. The key element of this dichotomy is the dielectric adjustment of specific transannular interactions between Se and CO group in the cation radicals. A series of alkyl arylselenides with pending carboxy or acetamido substituents was studied by cyclic voltammetry, IR spectroscopy and DFT calculation in binary solvents covering the span of polarity 8 2Se 2.
Bifunctional Chiral Auxiliaries 5: The Synthesis of 1,3-Diacylimidazolidine-2-thiones and 1,3-Diacylimidazolidin-2-ones from 1,2-Diamines

Although 1,2-diamines fail to cyclise with urea, phosgene or 1,1'-carbonyl diimidazole, they react with carbon disulphide to give the corresponding imidazolidine-2-thiones.These undergo clean diacylation to give 1,3-diacylimidazolidine-2-thiones which are
