Abstract
สาร N-(3-,4-และ5-) พิแรโซลิล-1,2,4-ไทรอะโซโล (1,5-C)พิริมิดีน-2- ซัลโฟแนมีด, ซึ่งถูกแทนที่บนวงพิริมิดีนด้วย หมู่ แอลคอกซิและบนวงพิแรซีน เช่น M-(4-โบร-1-เมธิลพิแร โซล-3-อิล)-7 -คลอโร-5-เมธอกซิ-1,2,4-ไทรอะโซโล 1,5-c พิริมิดีน-2- ซัลโฟแนมีด, เตรียมได้จาก 1,2,4-ไทรอะโซโล (1,5-c)พิริมิ ดีน-2- ซัลโฟนิลเฮไลด์ ซึ่งถูกแทนที่ด้วยแอลคอกซิ โดยให้ทำปฎิ กิริยา รวมตัวกับซับสทิทิวเทด (3-,4-และ5-)-อะมิโนพิแรโซล โดยมี ด่าง ที่เป็นพิริดีนและไดเมธิล ซัลฟอกไซด์ในปริมาณที่มีผลต่อการ เร่ง ปฏิกิริยาอยู่ด้วย พบว่าสารประกอบเหล่านี้ให้การออกฤทธิ์ ฆ่า วัชพืชโดยทั่วไป และในบางกรณีเลือกการออกฤทธิ์ฆ่าวัชพืชใน ระยะ ก่อนและหลังงอก สิทธิบัตรยา Substances N- (3-, 4- and 5-) pirazole-1,2,4-triazolo (1,5-C) Pyrimidine-2-Sulfonamid, which was replaced on the pirimidine band with the alkoxi group and on the pirateine band such as M- (4- Bro-1-methylpirazole-3-il) -7 - Chloro-5-Methoxy-1,2,4-triazolo 1,5-c Pyrimidine - 2- sulfonamides, prepared from 1,2,4-triazolo. (1,5-c) Pyrimidine-2-Sulfonyl Halide Which was replaced by the Alcoxin by the reaction to reunite with Substitut Ted (3-, 4- and 5 -) - aminopyresol, with bases being pyridine and dimethyl Sulfoxides in amounts that have an effect on the catalyst. It was found that these compounds act to kill weeds in general. And, in some cases, the weed-killing action was chosen before and after germination.
