We propose a new route to achieve the superconducting state in Boron-rich solids, the hole doping of B12 icosahedra. For this purpose we consider a prototype metallic phase of B13C2. We show that in this compound the Boron icosahedral units are mainly responsible for the large phonon frequencies logarithmic average, 65.8 meV, and the moderate electron-phonon coupling 0.8. We suggest that this high critical temperature could be a general feature of hole doped boron icosahedral solids.
