标题:Dimethoxypyrimidines As Novel Herbicides. Part 1. Synthesis And Herbicidal Activity Of Dimethoxyphenoxyphenoxypyrimidines And Analogues
摘要:A Number Of 6-(4-Phenoxyphenoxy)Pyrimidines And Triazines Were Synthesized And Their Herbicidal Activity Was Measured. Compounds With The Methoxy Groups At The 2-And 4-Positions On The Pyrimidine And Triazine Rings Exhibited High Herbicidal Activity. Introduction Of A Substituent Into The 5-Position Of The Pyrimidine Ring Diminished The Activity. In The Phenoxyphenoxy Substructure At The 6-Position,The Central Ether Bond Can Be Replaced By A Methylene Group Without Loss Of Activity. The Optimum Substituent On The Terminal Phenyl Ring Was 3-Trifluoromethyl. The Compounds Showed A Strong Hill Reaction Inhibition,But Unfortunately Showed Poor Selectivity Between Weeds And Crops.
