Aminosilanes bearing bulky substituents on nitrogen centers, [(ArNH)2SiPh2] (Ar=2,6-iPr2C6H3 (1), 2,4,6-Me3C6H2 (2), 2,6-Et2C6H3 (3)), have been prepared in good yields by the addition of dichlorodiphenylsilane to the corresponding substituted monolithiated aniline. The new compounds have been characterized by elemental analysis and IR, EI mass and NMR (1H and 29Si) spectroscopic studies. The solid-state structures of 1 and 3 have been determined by single crystal X-ray diffraction studies. The molecules have a Cs symmetry and the two N-H protons are approximately trans to each other. The amido nitrogen atoms show significant deviation from trigonal-planar geometry, as a result of which the observed Si-N bonds are marginally longer than those observed in aminosilanes with planar nitrogen atoms.
Alkaline-Earth-Catalysed Cross-Dehydrocoupling of Amines and Hydrosilanes: Reactivity Trends, Scope and Mechanism

Alkaline-earth (Ae=Ca, Sr, Ba) complexes are shown to catalyse the chemoselective cross-dehydrocoupling (CDC) of amines and hydrosilanes. Key trends were delineated in the benchmark couplings of Ph3SiH with pyrrolidine or tBuNH2. Ae{
Magnesium-mediated benzothiazole activation: A room-temperature cascade of C-H deprotonation, C-C coupling, ring-opening, and nucleophilic addition reactions

Ligand domin(o)ated: In contrast to the straightforward deprotonation of benzothiazole using Grignard reagents, treatment of benzothiazole with 1 leads to a novel type of activation. The initial magnesiation initiates an unstoppable domino reaction of C-C coupling, ring opening, nucleophilic addition, and deprotonation to give 2. THF=tetrahydrofuran. Copyright
