In the 1970s Hawthorne reported an electrochemical dehydrocoupling reaction of closo-carborane anion [HCB9H91–] 1 to form biscarborane [C2B18H182–] 2. this Communication we show that said "Hawthorne Reaction" can be achieved thermally and it tolerates C-butylation. The new compound 2butyl was fully characterized by 11B, 1H, 13C NMR spectroscopies, high-resolution mass spectrometry, single-crystal X-ray diffraction. One interesting caveat is 2 or only when they are salts Li+ not NEt4+, Na+, K+, Cs+. This observation means in some way facilitates process, introducing a kind effect.
