Helpful frustration : The geminal phosphorus/aluminum‐based frustrated Lewis pair (Mes 2 P)( t Bu 2 Al)CC(H)Ph (Mes=2,4,6‐Me 3 C 6 H 2 ) forms stable adducts with alkali metal hydrides (LiH, NaH, KH). These molecular hydride complexes display enhanced reactivity, which was demonstrated by the catalytic transformation of chlorotriphenylsilane to the corresponding hydride through a frontside S N 2‐f@Si pathway.
