Protonation of the highly reactive 1:1-intermediate produced in the reaction between triphenylphosphine and dimethyl acetylenedicarboxylate by naphthols lead to vinyl triphenylphosphonium salts which undergo an aromatic electrophilic substitution reaction with the conjugated base to produce the title compounds.
