Abstract [en]

Reactions of decarborane with various aldehydes in alkaline media were studied. The reactions with HCOH and 2-MeOC6H4-CHO give the corresponding arachno-carboranes [6-R-arachno-CB9H13]-(R=H, C6H4-2-OMe), whereas the reactions with C6H5CHO, 4-BrC6H4CHO, 4-MeCONHC6H4CHO and 2-SC4H3CHO result in the nido-carboranes [6-R-nido-CB9H11]-(R=C6H5, C6H4-4Br, C6H4-4-NHCOMe, 2-SC4H3). Both the arachno- and nido-carboranes can be easily oxidized with elemental iodine in an alkaline aqueous solution giving the corresponding closo-derivatives [2-R-closo-2-CB9H9]-. These closo-2isomers, under heating in solution, undergo rearrangement to more thermodynamically favorable closo-1-isomers [1-R-closo-1-CB9H9]-. The structure of (Bu4N)[1-(4-BrC6H4)-1-CB9H9] was determined using single crystal X-ray diffraction.
