Towards functional phospholide ions: synthesis of a 3-ethoxycarbonyl derivative

Palladium (O)-catalyzed insertion of ethyl propiolate into the ring of the 1--2,3-diphenylphosphirene P-W(CO)5 complex affords the corresponding 1--2,3-diphenyl-4-ethoxycarbonylphosphole complex.Phosphole decomplexation is achieved by heating with 1,2-bis(diphenylphosphino)ethane.A strong base (iPr2NLi or tBuOK) induces the quantitative cleavage of the exocyclic P-C bond of this phosphole to give the 2,3-diphenyl-4-ethoxycarbonylphospholide anion, which was characterized by 31P NMR spectroscopy and P-methylation. - Keywords: phosphole / phospholide ion : 3-ethoxycarbonyl derivative / phosphirene: alkyne insertion / terminal phosphinidene complex : β-cyanoethyl / (β-ethoxycarbonyl)ethyl / palladium : phosphine complex as catalyst / phosphine decomplexation
