Disclosed are novel 2,3-dihydro-3,3-dimethyl-5-trifluoromethanesulfonyloxy benzofurans and herbicides containing them, which are produced, e.g., via the mono-substituted 2-morpholino derivative, by reacting a corresponding 5-hydroxy benzofuran with a trifluoromethanesulfonyl esterifying agent.
本发明公开了新型 2,3-二氢-3,3-二甲基-5-三氟甲烷磺酰氧基苯并呋喃及其除草剂,这些除草剂是通过相应的 5-羟基苯并呋喃与三氟甲烷磺酰酯化剂反应,例如通过单取代 2-吗啉基衍生物制得的。
