Reaction between ortho-carborane and anhydrous AlCl3 in chloroform produces a mixture of derivatives with different substituents, with 9,12-dichloro-ortho-carborane being the main product. The crystal structure of 9,12-dichloro-ortho-carborane was determined by single crystal X-ray diffraction, and it is nearly isostructural to 9,12-dibromo-ortho-carborane. A synthetic scheme for preparing the hexachloro derivative of cobalt bis(dicarbollide) from 9,12-dichloro-ortho-carborane has been proposed.
Reaction of ortho-carborane with anhydrous AlCl3 in chloroform results in a mixture of 9-chloro, 9,12-dichloro, and 8,9,12-trichloro derivatives with 9,12-dichloro-ortho-carborane being the main product. Molecular crystal structure of 9,12-dichloro-ortho-carborane was determined by the single crystal X-ray diffraction. The crystal structure of 9,12-Cl-2-1,2-C2B10H10 appeared to be nearly isostructural to 9,12-dibromo-ortho-carborane: the crystal packing is built of layers in which molecules are connected via weak hydrogen and halogen bonds. A synthetic scheme for preparation of the hexachloro derivative of cobalt bis(dicarbollide) Cs[8,8 ',9,9 ',12,12 '-Cl-6-3,3 '-Co(1,2-C2B9H8)(2)] from 9,12-dichloro-ortho-carborane has been proposed.
