Eficient procedures are described leading to pure 3,4-R', R2-substituted I , l-diphenyl-2,5-dihydrophospholium salts (R' = R2 = CH,, H; R' = CH,, R2 = H). Their behaviors toward bases such as nBuLi and t- BuOK in THF or DMSO have been examined. According to the nature of the substituents R' and R2,
