A nonclassical carbon atom of a dicarbaborane is converted into a classical carbon atom, and the substituent increases in length by one CH 2 group (see scheme). This is the path followed to form [1‐Me‐6‐Et‐1‐ closo ‐CB 9 H 8 ] − regioselectively from [1,2‐Me 2 ‐1,2‐ closo ‐C 2 B 10 H 10 ]. First, the o ‐carborane derivative is reduced to [7‐Me‐μ‐(9,10‐HMeC)‐7‐ nido ‐CB 10 H 11 ] − , and then a carbon‐atom extrusion followed by selective deboronation takes place.
