The challenging metal‐free catalytic hydrogenolysis of silyl chlorides to hydrosilanes is unlocked by using an inverse frustrated Lewis pair (FLP), combining a mild Lewis acid (Cy 2 BCl) and a strong phosphazene base (BTPP) in mild conditions (10 bar of H 2 , r. t.). In the presence of a stoichiometric amount of the base, the hydrosilanes R 3 SiH (R=Me, Et, Ph) are generated in moderate to high yields (up to 95 %) from their chlorinated counterparts. A selective formation of the valuable difunctional monohydride Me 2 SiHCl is also obtained from Me 2 SiCl 2 . A mechanism is proposed based on stoichiometric experiments and DFT calculations; it highlights the critical role of borohydride species generated by the heterolytic splitting of H 2 .
