摘要：
Protonation of the reactive intermediate produced in the reaction between triphenyl phosphite and dimethyl acetylenedicarboxylate by 5,5-dimethylcyclohexane-1,3-dione leads to vinyltriphenoxy-phosphonium cation, which undergoes an addition reaction with the enolate anion of the CH-acid to produce the title compound in high yield.
