Selenoamides with two reactive sites: synthesis, structures, and dual reactivity of (selenocarbamoyl)phosphines

Abstract

Selenoamides stabilized by a phosphino group, i.e., (selenocarbonyl)phosphines, were synthesized and their solid-state structures were crystallographically determined for the first time. These (selenocarbamoyl)phosphines exhibit dual reactivity on two principal sites in reactions with electrophiles, i.e., on the phosphorus and selenium atoms, whereby the site where the reaction occurs depends on the nature of the reagent.
