Dibenzoylmethane dibromide (5) and 1,3-indandione dibromide (6) react with ylide-phosphoranes 1a-c to give the α,β-unsaturated esters 10 and 13, respectively.All intermediates are isolated and identified.Structures 10 and 13 as well as the intermediates were confirmed by compatible analytical and spectroscopic results.
