2,3-Diiodophenol is a chemical compound that belongs to both the phenols and the halogen aromatic compounds .
presentation
2,3-Diiodophenol can be prepared from 3-Iodophenol , from which N, N-Diethylcarbamate, which is a strongly ortho-directing group, is initially formed. This is followed by a selective lithiation at position 2 with butyllithium and tetramethylenediamine . Finally, the end product is formed by reaction with iodine .
Derivatives
The methyl ether can be produced by methylation with dimethyl sulfate and is also known under the common name 2,3-diiodanisole (CAS number: 98991-10-7). Its melting point is 74–75 ° C.
