Abstract: Phenylthiourea was reacted with trichlorophosphine and aldehydes(ketones) to produce 3-phenyl-4-chloro-4-oxo-1,3,4-diazaphospholidin-2-thione(Ⅰ). The compounds Ⅰ were then reacted with phenols to produce the titled compounds Ⅲ. The structures of compounds Ⅲ were comfirmed by 1H NMR,31P NMR and elemental analysis. The biological tests found that compounds Ⅲ have good selective herbicidal activities.

Key words: diazaphospholidinthione, phenol, herbicidal activity
