Abstract:
Cycles, not chains: 1-imidazolylboranes exist in polymeric form as a consequence of donor/acceptor interactions. Through the use of suitable substituents and under high dilution tetrameric and pentameric macrocyclic imidazolylboranes were synthesized. The picture shows the structure of the tetrameric 4,5-dimethylimidazolylborane (black: C, gray: B, white: N).
