, p. 131 - 134 (1992)
The reaction of phosphonate carbanions with elemental selenium in the presence of amines afforded the corresponding selenoamides in moderate yields.The reaction of these anions with sulfur also gave thioamides.These reactions might proceed through thio- or selenoaldehyde intermediates.

Copper(0)-induced aminocyclopropanation of olefins via deselenation of N,N-disubstituted aromatic selenoamides
Mitamura, Takenori,Nomoto, Akihiro,Sonoda, Motohiro,Ogawa, Akiya
experimental part, p. 9983 - 9988 (2009/04/03)
Upon heating of a mixture of N,N-disubstituted aromatic selenoamides and several electron-deficient olefins in the presence of copper(0) powder, a novel deselenative cyclopropanation takes place to afford the corresponding aminocyclopropanes in good yields. When acrylonitrile is employed as an electron-deficient olefin, the aminocyclopentanation occurs in preference to the aminocyclopropanation by prolonging the reaction time. The obtained aminocyclopropane derivatives can be converted to the corresponding 1,4-dicarbonyl compounds upon treatment with 2 N HCl.
