β-Carbonylsilanes with a silacyclohexane skeleton and additional C-functionalized organyl groups at the silicon atom: synthesis, reactivity, and NMR-spectroscopic characterization

The novel β-carbonylsilanes 1-8 (X/R = Cl/CH2Ph, N3/CH2Ph, Cl/tBu, N3/tBu, Cl/SiMe3, I/tBu, NCO/tBu, N(H)C(O)OtBu/tBu) were synthesized and studied for their reactivity. In addition, the disiloxane 11 was prepared, and 11 · 2H2O was structurally characterized by single-crystal X-ray diffraction.
