Abstract : 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 (1)H nmr data. (Author)
