چکیده
|
The present work deals with the synthesis of 4h-3,1-benzoxazin-4-ones carrying an aryl functional group at position-2. synthesized compounds tested for herbicidal activity at three different doses (500 μg/ml,50 μg/ml and 5μg/ml). most of the compounds exhibited significant herbicidal activity against lemna aequinocitalis welv. at higher dose (500 μg/ml). among the tested compounds 2-phenyl-4h-3,1-benzoxazin-4-one (3a) and 2-(3-chlorophenyl)- 4h-3,1-benzoxazin-4- one (3l) completely inhibited the plant growth at 500 and 50 μg/ml concentrations. all the synthetic compounds were characterized by ft-ir,1h nmr,ei-ms and elemental analysis.
