, p. 10087 - 10096 (2007/10/03)
Oximes possessing γ- δ or ω-alkenyl substituents are cyclised by phenylselenyl bromide, or by phenylselenyl chloride and an appropriate silver salt to the corresponding cyclic nitrones; the seleno nitrones undergo facially specific cycloaddition reactions with N-methylmaleimide; bis(alk-γ,δ-enyl) ketones undergo regiospecific cyclisation and stereospecific intramolecular cycloaddition to furnish spirocyclic products.

A strongly electrophilic phenylselenenylating agent is produced from the reaction of diphenyl diselenide with ammonium persulfate, in the presence of trifluoromethanesulfonic acid, in acetonitrile or nitromethane, at room temperature.This reagent induces
Phenylselenyl Halide Induced Formation of Cyclic Nitrones from Alkenyl Oximes
Grigg, Ronald,Hadjisoteriou, Maria,Kennewell, Peter,Markandu, Jasothara
, p. 1537 - 1538 (2007/10/02)
Oximes possessing alk-γ- or -δ-enyl substituents are cyclised by phenylselenyl bromide, or by phenylselenyl chloride and an appropriate silver salt, to the corresponding cyclic nitrones; the seleno nitrones undergo facially specific cycloadditions with N-methylmaleimide, bis(alk-γ,δ-enyl) and bis(alk-δ,δ-enyl) ketones undergo regiospecific cyclisation and stereospecific cycloaddition to furnish spirocyclic products.
