1-ALKYL-4-[(3-OXETANYL-)BENZOYL]-5-HYDROXYPYRAZOLE COMPOUNDS AND THEIR USE AS HERBICIDES

摘要

1-Alkyl-4-benzoyl-5-hydroxy-1H-pyrazole compounds of formula (I): in which the benzoyl moiety is substituted in the 2-position with groups such as halo or alkyl, in the 4-position with an alkylsulfonyl group, and in the 3-position with a 3-oxetanyloxy or an oxetanylmethoxy substituent were prepared and found to be useful for the control of a variety of broadleaf and grassy weeds. The herbicidal compounds have favorable environmental and toxicological properties and can be used to control undesirable vegetation in crops.
