A novel and convenient synthesis of diethyl [nitro(diazo)methyl]phosphonate
and its reactions with various alkenes are described. The reactivity
of diethyl [nitro(diazo)methyl]phosphonate is
shown to be dependent on the structure of the alkene. A number of
cyclopropyl α-nitrophosphonates were obtained.
