Sulfonyl urea derivatives of formula (I) are prepared. Thus substituted arylamines, aralkyl amines or amines containing hetero compounds are dissolved with HCl or H2SO4, and then are reacted with alkali solution of sulfonyl carbamates. In the formula (I), R=H, halogen, acetamino, amino or C1-4 alkyl, C1 carbonyl, C1-2 alkoxycarbonyl; R',R"= (i) H, phenyl, benzyl, substd. aryl, substd. benzyl, (ii) H, pyrimidine, triazin, substd. pyrimidine, substd. triazin, or (iii) H, C1-4 alkyl, C3-7 cycloalkyl. (I) are useful as herbicides.
