A compound characterised in that it corresponds to the following general formula:
wherein
R represents C1-C4 haloalkyl;
R1 represents hydrogen or C1-C4 alkyl; and
R2 represents C2-C8 cyanoalkyl, C5-C12 cyanoalkylcycloalkyl, C5-C12 cyanocycloalkyl, C3-C6 cyanoalkylalkoxy or cyanobenzyl;
provided that, when R2 represents cyanoalkyl, R repres- entsdibromoalkyl; is disclosed.
The above compounds may be prepared by reacting an appropriate nitrile amine or salt thereof with an appropriate halogenated acid chloride.
The use of the above compounds reduces the injury to desired vegetation caused by herbicides, more particularly thiocarbamates and haloacetanilides.
Compositions comprising such antidotes and such herbicides are also disclosed.
一种化合物,其特征在于它符合以下通式:
其中
R 代表 C1-C4 卤代烷基;
R1 代表氢或 C1-C4 烷基;及
R2代表C2-C8氰基烷基、C5-C12氰基环烷基、C5-C12氰基环烷基、C3-C6氰基烷氧基或氰基苄基;
但当 R2 代表氰基烷基时,R 代表二溴烷基。
上述化合物可通过适当的腈胺或其盐与适当的卤代氯化酸反应制备。
使用上述化合物可减少除草剂,特别是硫代氨基甲酸酯类和卤代乙酰苯胺类除草剂对所需植被造成的伤害。
此外,还公开了包含此类解毒剂和此类除草剂的组合物。
