Abstract

NEW MATERIAL:The compound of formula I (X is H or halogen; R is lower alkyl or phenyl). EXAMPLE:Phenyl N-[2-(2-chlorophenoxy)-phenylsulfonyl]carbamate. USE:A herbicide exhibiting excellent activity against the weeds in plowed land such as white-bird's-eye, barnyard grass, etc. and the weeds in paddy field such as unbrella plant, water-wort, etc., and free from phytotoxicity to paddy rice plant. PREPARATION:The compound of formula I can be prepared by reacting the compound of formula II [e.g. 2-(2-chlorophenoxy)benzenesulfonamide] with the compound of formula III (R' is Cl or -O-R) (e.g. diphenyl carbonate) in a solvent such as dimethylformamide, if necessary in the presence of an acid acceptor (e.g. sodium hydride), at 0-100 deg.C.
