Sixteen novel 3,6-dialkylthio-1-phenyl-pyrazolo[3,4-d]pyrimidin-4-ones were synthesized from the intermediate 3-alkylthio-1-phenyl-pyrazolo[3,4-d]pyrimidin-6-thiones and RX or BrR Br. All com-pounds synthesized were identified by 1H NMR, IR and MS techniques. Preliminary bioassay results show that some of these compounds have better inhibitory effect against the roots of rape and barnyard grass.

Key words: pyrazolo[3,4-d]pyrimidin-4-one, sythesis, herbicide
