Set Me 3 SiH free! The strong Lewis acid B(C 6 F 5 ) 3 catalyzes the release of hydrosilanes from 3‐silylated cyclohexa‐1,4‐dienes with concomitant formation of benzene. Subsequent B(C 6 F 5 ) 3 ‐catalyzed SiH bond activation allows for alkene hydrosilylation (see scheme). The net reaction is an ionic transfer hydrosilylation. The new technique is particularly attractive in the case of otherwise gaseous, highly flammable hydrosilanes.
