N-cycloalkyldithio-N'-fluorophenyl ureas are useful for eliminating grassy and broadleaf weeds selectively from crop plants such as corn, sorghum and potatoes. The ureas are prepared by reacting an N-clorothio-N'-fluorophenyl urea with a cycloalkyl mercaptan in the presence of an acid acceptor.
N-环烷基二硫-N'-氟苯基脲对于从玉米、高粱和马铃薯等作物中选择性地消除草本和阔叶杂草非常有用。这些脲类化合物是通过在酸受体存在的情况下将N-氯硫基-N'-氟苯基脲与环烷基巯基反应制备而成的。
