P-centered ring-opening of quaternary phosphirenium salts (QPrS) predominantly leads to hydrophosphorylated products, while the C-centered ring-opening results mainly in the formation of phosphorus-containing cyclization products. Here the authors synthesize β-functionalized vinylphosphine oxides by the P addition of QPrS intermediates generated in situ.
