Carborane 1, 2-dicarbaclovododecaborane

Methylcarborane [l-methyl-l,2-dicarbaclovododecaborane-(12)] may be prepared by hydrolysis of the Grignard reagent formed from the reaction of (bromomethyl)carborane with magnesium in the presence of diethyl ether.2c B h... 

The selective basic degradation of 1,2-dicarbaclovodode-carborane(12) and its C-methyl and C-phenyl derivatives has been recently reported.3 The ethanolic potassium hydroxide degradation of C, C"-dimethyl-l, 2-dicarbaclovododecaborane (12) and the isolation of the trimethylammonium salt of the resulting B9C2Hio(CH3)2 anion are described here as an illustration of this general reaction. The properties of the trimethylam-... 

Neocarborane 1,7-Dicarbaclovododecaborane As with carborane, neocarborane undergoes facile stepwise metallation with lithium alkyls to give the synthetically useful C-lithio- and C,C-dilithloneocarboranes.
