Based on the previously described bifunctional Lewis acid with a functional distance of the boron functions of 4.918(2) ?, the development of a further bifunctional, boron-containing Lewis acid with a wider functional distance is demonstrated. Again, a st

Three bifunctional boron-Lewis acids based on a 1,2-diethynylbenzene backbone were synthesized using a tin-boron exchange protocol in good to very good yields. Complexation experiments with pyrimidine were thoroughly investigated using the example of 1,2-bis(benzo[d][1,3,2]dioxaborol-2-ylethynyl)benzene (3) in solution, in the solid phase and by quantum-chemical calculations. Two adducts were structurally investigated by X-ray diffraction experiments. DOSY-/VT-NMR experiments gave insight into the dynamic behaviour of the synthesized poly-Lewis acids with pyrimidine.
