| Abstract: | Herbicides sulfonylurea such as thifensulfuronmethyl and tribe-nuronmethyl were synthesized by bis(trichloromethyl)carbonate (BTC) as a phosgene substitute. Under the optimum reaction conditions, the thifensulfuronmethyl with 96.3% purity in overall yield 83.3% and the tribenuronmethyl with 97.2% purity in overall yield 85.4% based on corresponding sulfamides were obtained. |
