Abstract

The potential of our metal-free B–C coupling method using catalytic Si/B exchange condensation is demonstrated by the synthesis of a series of monodisperse (het)arylborane oligomers with four (het)arene moieties and three boron centers (i.e., ‘trimers’). Photophysical and electrochemical investigations evidenced effective π-conjugation over the (het)arene rings and the boron centers.

  • 17 A trimer with three furan rings could only be detected by mass spectrometry, see ref. 12b.
  • 18 Compound 1b was generated and reacted in situ.
  • 19 Reactions of 1b with 4a,b did not yield conclusive results, presumably because of the poor stability of 1b.
