Nitration of 1,2-Unsaturated Phosphoryl Compounds with Dinitrogen Tetraoxide

Baranov

, p. 1481 - 1484 (2007/10/03)

Nitration of 1,2-unsaturated phosphoryl compounds with dinitrogen tetraoxide, depending on the substituents at the double bond and phosphorus atom, yields 1-hydroxy-2-nitro- or 2-hydroxy-1-nitroethyl-phosphonates or is accompanied by rupture of the C-C and C-P bonds. 1-Haloethenylphosphonates give rise to either dinitro derivatives or dialkyl 1-bromo-2-nitroethyl phosphates and dialkyl nitroacetylphosphonates.
