Abstract
Diethynyldiphenylsilane (1) and divinyldiphenylsilane (2) were functionalized by hydrosilylation reactions with HSiMe2Cl, HSiMeCl2 and HSiCl3. Fluorination of the resulting compounds generates bidentate openchain Lewis acids of increasing acidity. All semi-flexible [Ph2Si(CH=CHSiFnMe3-n)(2) (n = 1, 2, 3)] and flexible [Ph2Si(CH2 CH2SiFnMe3-n)(2) (n = 1, 2, 3)] bidentate Lewis acids were obtained in good to excellent yields. The different fluoride ion complexation behavior was explored in detail by multinuclear (low temperature) NMR spectroscopy. The Lewis acidic bidentate molecules as well as the resulting mono- and bissilicates were completely characterized by NMR spectroscopy, mass spectrometry and in part by elemental analysis and X- ray diffraction experiments.
