摘要 NEW MATERIAL:A compound of formula I (R is aryl, heteroaryl, alkyl which may be substituted; R<1>, R<2> are H, alkyl; R<3> are aryl, alkyl which may be substituted; R<4> is aryl, heteroaryl which may be substituted). EXAMPLE:N-(2,2-Dimethyl-1-phenyl)ethenyl-N-(2'-methoxyethyl)benzenesul fonami de. USE:Herbicide and fungicide. It shows high herbicidal activity and selectivity. It can effectively control weeds in water rice paddies with high safety to rice plant. PREPARATION:The reaction of an imino of formula II with a sulfonic acid halide or anhydride of formula III (Z is halogen, OSO2R<4>, OSO2CF3) gives the compound of formula I. The reaction is carried out in an organic solvent such as benzene at -20-150 deg.C, preferably at 0-100 deg.C.
