双（脒基）亚甲硅烷基[iPrNC（Ph）-NiPr]（2）Si和类似的双（胍基）亚甲硅烷基[iPrNC-（NiPr 2）NiPr]（2）Si与刘易斯酸BPh 3和AlPh 3反应以形成相应的刘易斯酸/碱加合物4-7（加合物4已经描述）。化合物5和7是第一亚甲硅烷基-铝烷加合物和具有Si-Al键的第一五配位硅（II）化合物，并且6和7分别表示衍生自双（胍基）亚甲硅烷基的第一亚甲硅烷基-硼烷和亚甲硅烷基-铝烷加合物。化合物4-7通过单晶X射线衍射和固态NMR光谱（B-11、N-15、Al-27、Si-29）表征，并且4和5另外通过溶液中的NMR光谱（H-1、B-11、C-13、Al-27、Si-29）研究。
The bis(amidinato)silylene [iPrNC(Ph)-NiPr](2)Si and the analogous bis(guanidinato)silylene [iPrNC-(NiPr2)NiPr](2)Si react with the Lewis acids BPh3 and AlPh3 to form the respective Lewis acid/base adducts 4-7 (adduct 4 has already been described). Compounds 5 and 7 are the first silylene-alane adducts and the first five-coordinate silicon(II) compounds with an Si-Al bond, and 6 and 7 represent the first silylene-borane and silylene-alane adducts, respectively, that are derived from a bis(guanidinato)silylene. Compounds 4-7 were characterized by single-crystal X-ray diffraction and solid-state NMR spectroscopy (B-11, N-15, Al-27, Si-29), and 4 and 5 were additionally studied by NMR spectroscopy in solution (H-1, B-11, C-13, Al-27, Si-29).
