presented from the reaction of the neutral tri(tert-butyl)sulfur triimide S(NtBu)3 (1), nBuLi, and diisopropylaniline and dimethylaniline, respectively. These asymmetrically substituted hydrogen tetraimido sulfate complexes of lithium provide the opportunity to switch the metal in a transmetalation reaction and to introduce another substituent at the protonated imide function.

present the synthesis and structure of the basic starting material MeS(N(t)Bu)(3)H (1), the metal complexes [Me(2)Al(N(t)Bu)(3)SMe] (2) and [Zn[(N(t)Bu)(3)SMe](2)] (3), and the mixed metal adduct [(thf)Li[(N(t)Bu)(3)SMe].ZnMe(2)] (4). The chelating coordination, rather than the tripodal coordination, cannot be attributed to steric effects of the S-bonded methyl group, as the less demanding Ph-C triple
