A new synthetic approach enabled the generation of highly labile thionylimide, H−NSO, which was trapped by adduct formation with the bulky Lewis acid B(C 6 F 5 ) 3 and fully characterized. For comparison, a series of different Me 3 Si−NSO Lewis acid adducts were studied. Treatment of Me 3 Si−NSO with the silylium ion [Me 3 Si] + led to the formation of the hitherto unknown iminosulfonium ion [Me 3 Si−N=S−O−SiMe 3 ] + , which could be isolated and fully characterized as a salt in the presence of weakly coordinating carborate anions.
