2-bromine-5-nitro-1,2,3,4-tetrahydro-1,4-methano-naphthalene-9-phenol and preparation method thereof

The invention provides a chemical compound which can serve as an intermediate for benzovindiflupyr synthesis. The chemical compound is 2-bromine-5-nitro-1,2,3,4-tetrahydro-1,4-methano-naphthalene-9-phenol with the chemical formula as shown in formula (IV) in the specification. The invention further provides a method for preparing the chemical compound, 2-bromine-5-nitro-1,2,3,4-tetrahydro-1,4-methano-naphthalene-9-phenol. The method comprises: a chemical compound, [2,3]-epoxy-5-nitro-1,2,3,4-tetrahydro-1,4-methano-naphthalene, as shown in formula (III) reacts in a hydrobromic acid aqueous solution at 20 DEG C, and the chemical compound as shown in formula (IV) is prepared. The invention finds a novel method for producing a key intermediate for benzovindiflupyr and a preparation method thereof, thereby enabling the route for benzovindiflupyr synthesis to be more reasonable.
