β-phenylselenocarbonyl compounds by a one-pot reaction of diphenyldiselenide and α,β-unsaturated ketones, aldehydes, esters and nitriles in the presence of indium metal-trimethylsilyl chloride under sonication. Presumably, the In-TMSCl reagent system reacts with diphenyldiselenide to form an intermediate, PhSeSiMe3, which then undergoes Michael addition with the α,β-unsaturated carbonyl compounds to produce

The reduction of diphenyl diselenide by the SmâMe3SiClâH2O system led to a selenide anion. This âlivingâ species reacted with organic halides, epoxides, α,β-unsaturated esters and α,β-unsaturated nitriles to afford unsymmetrical phenylselenides in good yields under mild and neutral conditions.
