식 (I) 의 화합물과 그것의 염 및 에스테르는 : (식중 : R및 R는 각각 수소, 임의로 치환된 알킬, 임의로 치환된 알케닐, 알키닐, 알콕시, 아릴 또는 피리딜기를 나타내거나, 또는 R및 R가 함께 알킬렌을 나타내고 ; A 및 B 는 각각 수소, 할로겐, 임의로 치환된 알킬, 임의로 치환된 알케닐, 임의로 치환된 알콕시, 알킬티오, 알킬술폰일, 디알킬 술파모일, 지방족 카르복실아실, 카르복시, R및 R은 각각 수소 또는 알킬, 포르밀 또는 시아노기인 - CONRR이고 ; D 는 임의로 치환된 페닐, 벤질, 피리딜 또는 피리미딘일을 나타내고 ; n 은 0, 1 또는 2 이다 ) 중요한 제초 특성을 가지며, 그것들은 총체적으로 벼에 무해하기 때문에 논의 처리에 특히 유용하다. Compounds of formula (I): (in which: R and R are each hydrogen, optionally substituted alkyl, optionally substituted alkenyl, alkynyl, alkoxy, aryl or pyridyl, or R and R together represent alkylene; A and B are each hydrogen, halogen, optionally substituted alkyl, optionally substituted alkenyl, optionally substituted alkoxy, alkylthio, alkylsulphonyl, dialkylsulphamoyl, aliphatic carboxylic acyl, carboxy, -CONRR where R and R are each hydrogen or alkyl, formyl or cyano groups; D represents optionally substituted phenyl, benzyl, pyridyl or pyrimidinyl; and n is 0, 1 or 2; and salts and esters thereof) have valuable herbicidal properties, and, since they are totally innocuous to rice plants, are especially useful for the treatment of paddy fields.
