Bis(diisopropylamino)chloroborane and pure AlCl3 react under rigorously anhydrous conditions in a one to one ratio to give an ionic compound that can be formulated as [(i-Pr)2N=B=N(i-Pr)2]+[AlCl4] -. This representation is supported by 27Al, 1H, 13C, and 11B NMR data as well as by IR absorption bands at 1830-1900 cm-1 assigned to the B=N double bond. Conductivity data are also given for the related compound made from bis(dimethylamino)chloroborane. The [Me2N=B=NMe2]+ cation was not stable in solution. Evidence is interpreted in favor of either its condensation to bigger units and/or the formation of a molecular compound with the AlCl4- anion. Lewis base molecules will add to the tetramethyl cation to give a four-coordinate boron cation.
