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

The surface-mediated synthesis of epitaxially aligned and separated polyphenylene lines on Cu(110) by exploiting the Ullmann dehalogenation reaction is reported. Scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS) show that the C-I bonds of 1,4-diiodobenzene and 1,3-diiodobenzene (C(6)H(4)I(2)) are
