Phosphonium salts 3 obtained by the quaternisation of 1-aryl-2,5-dihydro-1H-phospholes 2 with methyl bromoacetate are suitable precursors of the corresponding heterocyclic phosphoranes 5. They were generated in situ using DBU at ambient temperature.

The title phosphonium ylides give an ylidene oxolactone under reductive conditions and are unreactive towards aldehydes, but are degraded by hydroxylamine to form the simpler acetic ester phosphonium ylides that do react with aldehydes in the normal
