Verbindungen der Siliciumtetrahalogenide mit aromatischen N‐Heterocyclen

Abstract: Im System Siliciumtetrahalogenid‐Pyridin werden von SiF4, SiCl4, SiBr4 und SiHCl3 unter beträchtlicher Wärmeentwicklung Verbindungen des Typs SiHlg4Py2, von SiJ4 allein eine Verbindung des Typs SiHlg4Py4 gebildet. Dem Pyridin verwandte Heterocyclen wie α‐Picolin, Collidin, Chinolin und Acridin reagieren nur mit SiJ4 zu Verbindungen der Zusammensetzung SiJ4 · 4 Chinolin (usw.). Methylchlorsilane sowie Kohlenstofftetrahalogenide verbinden sich nicht mehr mit Pyridin. Man kann auch nicht Thiophen an Stelle des Py… Show more

“…We now learned that the outcome of the reaction of the 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene with H 2 SiCl 2 , H 2 Si(OTf) 2 and H 3 SiOTf is depending on the nature of the substituents of the different hydrosilanes.…”

“…When H 2 Si(OTf) 2 was treated with an equivalent of the NHC in toluene at room temperature, a colorless precipitate was formed immediately. The 1 H NMR spectrum of the resulting mixture showed the formation of the desired 1 : 1 adduct (NHC)SiH 2 (OTf) 2 (3), which could be isolated in 75 % yield (Scheme 3).…”

“…Campbell-Ferguson and Ebsworth (1) recently confirmed that SiF4.2py is the only complex formed between silicon tetrafluoride and pyridine (abbreviated py in formulae), contrary to previous reports of SiF4.py (2, 3) and 2SiF4.3py (4) complexes. We had also found that under a variety of experimental conditions silicon tetrafluoride and pyridine produce only SiF, .2py (5).…”

“…Although the authors' methods were followed carefully, 2SiF4.3py (4) and SiF,.py (2, 3) could not be synthesized. Schnell (6) and, more recently, Campbeli-Ferguson and Ebsworth (1) obtained only the 1 : 2 complex.…”
