The reactions of the arachno-4,6-C 2B 7H 13 carborane with the secondary and primary amines, Me 2NHBH 3 and ( t )BuNH 2BH 3, in ionic liquid media result in both boron-insertion into the cage at a position across the two cage-carbons and additional hydrogen-elimination via the reaction of a hydridic B-H with a protonic amine N-H hydrogen to produce the 6-(RR'N)- nido-5,7-C 2B 8H 11 carboranes.
