One-pot synthesis of sterically congested phosphorus ylides

Article abstract of DOI:10.1080/10426509708033713

Protonation of the reactive 1:1 intermediates produced in the reaction between triphenylphosphine and dialkyl acetylenedicarboxylates by 1,3-diphenylpropane-1,3-dione leads to vinylphosphonium salts, which undergo Michael addition with the conjugate base of the CH-acid to produce highly functionalized salt-free phosphorus ylides in excellent yields.
