Abstract

The new boron dihalides of the type [HC(CMe)₂(NC ₆F₅)₂]BX₂ (X = Cl, Br, I) have been prepared and characterized by single-crystal X-ray diffraction. Of the various synthetic approaches explored, the best method in terms of yield and product purity involves the silylhalide elimination reaction of the silylated iminoamine [HC(CMe)₂(NC₆F₅)(N{SiMe₃}C ₆F₅)] with BX₃. Chloroborenium salt [HC(CMe)₂(NC₆F₅)₂BCl][AlCl ₄] was prepared by treatment of [HC(CMe)₂(NC ₆F₅)₂]BCl₂ with AlCl₃ in CH₂Cl₂ solution. This salt was also structurally authenticated and represents the first such data for a β-diketiminate- supported haloborenium cation.
