Abstract

The new boron dihalides of the type [HC(CMe) < inf > 2 < /inf > (NC < inf > 6 < /inf > F < inf > 5 < /inf > ) < inf > 2 < /inf > ]BX < inf > 2 < /inf > (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) < inf > 2 < /inf > (NC < inf > 6 < /inf > F < inf > 5 < /inf > )(N{SiMe < inf > 3 < /inf > }C < inf > 6 < /inf > F < inf > 5 < /inf > )] with BX < inf > 3 < /inf > . Chloroborenium salt [HC(CMe) < inf > 2 < /inf > (NC < inf > 6 < /inf > F < inf > 5 < /inf > ) < inf > 2 < /inf > BCl][AlCl < inf > 4 < /inf > ] was prepared by treatment of [HC(CMe) < inf > 2 < /inf > (NC < inf > 6 < /inf > F < inf > 5 < /inf > ) < inf > 2 < /inf > ]BCl < inf > 2 < /inf > with AlCl < inf > 3 < /inf > in CH < inf > 2 < /inf > Cl < inf > 2 < /inf > solution.
