二(三氯甲基)碳酸酯“一锅法”合成1-芳基-3,3-二甲基脲除草剂
One-pot Preparation of 1-Aryl-3,3-dimethylureas Herbicides Utilizing Bis(trichloromethyl)carbonate
【摘要】 用二(三氯甲基)碳酸酯(BTC)替代光气,“一锅法”合成了有较好市场的过期专利取代脲除草剂异丙隆、伏草隆、绿麦隆、敌草隆、灭草隆等。BTC用量为0.4倍,收率为91%-95%,纯度为98%-99%。
【Abstract】 1-Aryl-3,3-dimethylureas herbicides, including isoproturon, fluometuron, chlorotoluron, diuron and monuron,. were synthesized by bis(trichloromethyl) carbonate (BTC). The usage of BTC was 0.4 equivalent to arylamine, The yields and purities of the products were 91%-95%and 98%-99%, respectively.
