The goals of this mini review constitute a) a presentation of the synthetic protocols applied to the preparation of achiral and non-racemic selenonium ylides; b) discussion of their basic structural features, including their optical activity; and c) a description of their synthetic applications in general synthetic methodology and in asymmetric synthesis.
Keywords: asymmetric synthesis; chirality; optical resolution; reactivity; selenonium salts; selenonium ylides; stereogenic selenium atom.
