Abstract
NEW MATERIAL:A substituted phenylsulfonyl isocyanate shown by the formula I(X is phenyl or phenoxy).
EXAMPLE: 2-Biphenylsulfonyl isocyanate.
USE: An intermediate for synthesizing a substituted phenylsulfonylurea derivative shown by the formula II[R is a group shown by the formula II or formula IV (R1 and R2 are methyl or methoxy)]having improved selective herbicidal activity.
PROCESS: A substituted phenylsulfonamide shown by the formula V is reacted with phosgene or trichloromethyl chloroformate in the presence of hydrocarbyl isocyanate to give a compound shown by the formulaI. The reaction is carried out in an inert solvent in the presence of a catalyst (e.g., TEA) at a reaction temperature of 80W150°C preferably at normal pressure, and it may be carried out under pressure or reduced pressure.
