Five new-O-polyhaloalkyl-O-substituted-phenyl- hydrazinophosphorates were synthesized and characterized by spectral data. In the presence of Et~3N, they are easily transferred into 1,3,4,2-oxadiazaphospholanes. The mechanism of the cylization of 1 to 2 was discussed. 1c and 2c showed a high activity against nematocides.
