Protonation of the reactive 1:1 intermediate produced in the reaction between triphenylphosphine and dialkyl acetylenedicarboxylates by CH-acids, such as dialkyl phthalimidomalonates and dimethyl Succinimidomalonate, leads to a vinylphosphonium salt, which undergoes intramolecular Wittig reaction to produce the title compounds in fairly high yields.
