Benn, Reinhard,Mynott, Richard,Richter, Wolf Juergen,Schroth, Gerhard

, p. 3273 - 3276 (1984)

The reaction of methylenetrimethylphosphorane with isomeric mixtures of cis and trans 1-t-butyl- or 1-cyclohexyl-2-vinylphosphirane produce new phosphino-substituted phosphorus ylids via ring-opening and proton transfer.The products are fully characterized by NMR.
