Synthesis of 1-HSCH2-1,2-C2B10H11 from B10H12(SR)2 and (CH3)3C-SCH2C C is described. A distinctly greater difference in acidity at the couple C6H5SH/1-HS-1,2-C2B10H11 (ΔpKa 4.20) in comparison with the couple C6H5CH2SH/1-HSCH2-1,2-C2B10H11 (ΔpKa 2.34) confirmed the great significance of a mesomeric acidification of the HS-group bound to a carborane framework.
