Six novel bis-benzoylphenylurea compounds have been synthesized from available compound chlorothalonil 1(2,4,5,6-tetrachloroisophthalonitrile) in yield of 30%~50%. The synthetic route has advantages of mild reaction ...
Chlorothalonil 1 was treated with anhydrous KF in DMF at 110 ℃ to give the corresponding crystalline fluorine-containing 1,3-benzenedicarbonitrile 2. KF was used in an equivalent to the number of chlorine atoms to be...
