2,3-Dihydro-3,3-dimethyl-5-trifluoromethanesulfonyloxybenzofurans, process for producing them and herbicides containing them.

摘要

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.
