The closo carborane 1,6-C2B4H6 reacts with trimethylamine to form 5-Me3N-nido-2,4-C2B4H6-. The latter compound rearranges in chloroform, or thermally, to the 3-Me3N - isomer. The parent 2,4-C2B4H7- ion is obtained both from the action of NaH on either 3- or 5-Me3N -2,4-C2B4H6- and from the slow reaction of closo-1,6-C1B4H6 with either NaH or LiH. The structure of 2,4-C2B4H7- and 2,3-C2B4H7- and the Me3N -2,4-C2B4H6- isomers are correlated with 11B and 1H nmr data. Author
