Synthesis of Organophosphorus Compounds Using Phase Transfer Catalysis

Abstract α-Hydroxyphosphonates, α-alkoxyphosphonates and mixed alkyl arylalkyl phosphates have been synthetised in phase transfer catalytic reactions. Cyclopropyl phosphates were prepared from vinyl phosphates by the addition of dihalocarbene. Monodealkylation of several phosphates and phosphonates were performed by solubilized halogenide aniones. PTC catalysis was used in the synthesis of unsymmetrically substituted carbodiimides via phosphoramidates.
