The striking reactivity of donor-stabilised silanone LSi(DMAP)O (1) [L = N(Ar)C(CH2)CHC(Me)N(Ar), Ar = 2,6-iPr2C6H 3, DMAP = p-dimethylaminopyridine] toward Lewis acidic metal substrates Zn(OAc)2, ZnMe2, and AlMe3 is reported. Two unprecedented addition products onto the SiO double bond, [LSi(OAc)(μ-O)Zn(OAc)(DMAP)2] (2) and [LSi(OAc)(μ-O)] 2Zn(DMAP) (3), and two terminal complexes LSi(DMAP)O→ZnMe 2 (4) and LSi(DMAP)O→AlMe3 (5) were obtained. Compounds 4 and 5 are unique, representing the first isolable and structurally characterised terminal SiO→Zn and SiO→Al complexes. All new compounds were fully characterised by 1H, 13C, and 29Si NMR spectroscopy, EI-MS, elemental analysis and single-crystal X-ray diffraction analyses. The Royal Society of Chemistry.
