Benzenetellurinyl trifluoroacetate readily reacts with alkenes in acetonitrile in the presence of boron trifluoride etherate at 75 °C to give 2-oxazolines via amidotellurinylation.
Camphorselenenylsulfate is an efficient chiral, nonracemic electrophilic reagent which can be produced from the easily available camphor diselenide by treatment with ammonium persulfate. This electrophilic selenium reagent reacts with alkenes, at room temperature in acetonitrile, in the presence of water and trifluoromethanesulfonic acid to afford the amidoselenenylation products with moderate facial
