Abstract

Two hydrophobic imidazolylidene-cyanoborane complexes were prepared by the introduction of {BH₂CN} into the molecular formula via treatment of imidazolium iodide and NaBH₃CN avoiding literature's tedious and hazardous procedures. These two complexes were fully characterized using IR spectroscopy, ¹H NMR and ¹³C NMR spectroscopy and high-resolution mass spectrometer. The X-Ray structure of NHC-1 has been determined. NHC-2 was proved to be hypergolic with WFNA and displayed the attractive properties such as water immiscibility, wide liquid range (T_g = −22 °C), short ignition delay time (13 ms), high density (0.98 g/cm³), good density impulse (ρI_sp, 347 s g cm⁻³), showing the promising application potential as a fuel and an efficient fuel additive.
