Abstract

NEW MATERIAL:A bisphosphonic acid compound shown by the formula I (R1 is H, alkyl, halogen; R2 is H or alkyl; X is O or NH) and its salt.
EXAMPLE: N-(5-isopropyl-3-isooxazolyl) aminomethylenediphosphonic acid.
USE: A herbicide having improved weeding effect in the treatment after germination. A herbicide for treating stalks and leaves, e.g., a herbicide of weeds in the fruit garden, a herbicide for a ridge between rice fields.
PROCESS: PCl3 is reacted with H3PO4 to give P2O3, which is reacted with a formylamino-pyrazole shown by the formula II, or formylamino-isooxazole at 30W70°C under heating to prepare a compound shown by the formula III. This compound is hydrolyzed to produce a compound shown by the formula I.
