Various metal complexes catalyze exchange between H 2 and hydrosilanes. Catalyst screening suggests that the electron deficiency of the metal center is necessary for exchange, but silane and/or hydrogen addition or σ‐bond metathesis with the M–Si and M–H bonds are not required. Kinetic measurements for the system [(ArN=)Mo(PMe 3 ) 3 (H)(SiH 2 Ph)/H 2 /H 3 SiPh] (Ar = 2,6‐ i Pr 2 C 6 H 3 ) suggest that the reaction proceeds through activation of the silane.
