Özet:

Weakly coordinating anions are extremely versatile species for capturing and characterizing cationic intermediates. Among these anions, carboranes and some boranes are known to be the most weakly coordinating anions. In this thesis, the carboranes and boranes were synthesized in order to capture and characterize unusual carbocations. B11H14-was synthesized from NaBH4. Undecaborate was converted to B10H14 by oxidation and extrusion of one boron vertex. The B10H14 was successfully converted to ortho-carborane. B11H14 -was treated with I2, and then B12H12 2-was synthesized. Dodecaborane and CB11H12 -were methylated on boron vertex to get B12Me12 2-and HCB11Me11 -. The methylated boranes and carborane cages are more hydrophobic and weakly coordinating anions.
