Abstract
NEW MATERIAL:A compound of formula I (R1 is 1W3C alkyl, allyl, benzyl, or substituted benzyl; R2 is 1W6C alkyl, 5W6C cycloalkyl, or benzyl).
USE: Herbicide for paddy rice field Effective against false pimpernel, toothcup, cockspur-glass, umbrella plant, etc. Low toxic to man, beast, fish, etc.
PROCESS: The compound of formula I is prepared by reacting the compound of formula II with the compound of formula R1X (X is Br, Cl or I) a sulfuric acid ester of formula (R1)2SO4. The reaction is pref. carried out in a solvent such as water, alcohol, etc., in the presence of a base (e.g. caustic soda, sodium carbonate) at 20W35°C. When the R1 in the formula I is a 1W3C alkyl, the objective compound can be obtained in higher yield by reacting the compound of formula II with the sulfuric acid ester.
