DOCUMENT TYPE: Journal CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Section cross-reference(s): 5 Aryl-3,3-dimethyl urea herbicides, including isoproturon, fluometuron, chlorotoluron, diuron and monuron, were synthesized from bis(trichloromethyl) carbonate (BTC). The usage of BTC was 0.4 equiv to arylamine. The products were confirmed by 1HNMR and IR. The yields and purities of the products were 91%-95% and 98%-99%, resp. .
