Description

General description

1,3-Diiodobenzene is a halogenated benzene derivative. Its reaction with phenylboronic acid in the presence of CuI, DABCO (1,4-diazabicyclo[2.2.2]octane) and TBAB (n-Bu₄NBr) has been analyzed. 1,3-Diiodobenzene undergoes coupling with 2-methylthiophene in the presence of Ir/Ag₂CO₃ to afford meta-linked isomer of thiophene-benzene-thiophene triad.

Application

1,3-Diiodobenzene may be used in the synthesis of:

• 3,5-bis(perfluorodecyl)phenylboronic acid
• epitaxially aligned and separated polyphenylene lines on Cu(110)
• 1,3-bis(4-ethynyl-2,5-dibutoxyphenyl-1-ethynyl)benzene
