Synthesis and structures of two new types of boronium salts

Transamination of di(pyrid-2-yl)amine (1) with B(NMe2) 3 leads to the isomeric heterocyclic bis(dimethylamino)boryl compound 4 and not to bis(diniethylamino)di(pyrid-2-yl)arninoborane (2). B(NMe 2)3 reacts with aniline (1:2 ratio) to yield a 1:1 mixture of B(NHPh)3 and (Me2N)2BNHPh. Transamination of this mixture with 1 yields the anihnodimethylamino analogue of 4 (compound 7). Compound 4 reacts with CHCl3 to generate the boronium salt 5 by the abstraction of HCl from CHCl3 and addition of HCl to one of the dimethylamino groups. Compound 5 crystallizes with 4 molecules of CHCl 3. Compound 4 is attacked by AlCl3 in toluene to give a mixture of unidentified products from which the tetrachloroaluminate of a new type of spirocyclic diboronium cation, 8, was isolated and characterized by X-ray crystallography.
