A metal‐free method for reduction of cyclic N ‐sulfonyl ketimines catalyzed by B(C 6 F 5 ) 3 , using commercially available methylphenylsilane as a reducing reagent under mild conditions has been developed. This reductive protocol was effective, not only providing the expected cyclic N ‐sulfonamides in good to excellent yields, but also showing good functional‐group tolerance.
