DIPHENYLDIFLUOROSILANE Chemical Properties,Uses,Production
Physical properties
bp 246–247 °C, bp 156°C50 mmHg, bp 66–70°C0.5 mmHg; d 1.155 g cm?1.
Uses
A moisture insensitive equivalent of diphenyldichlorosilane that is
more reactive toward nucleophiles. Source of phenyl group in the
Hiyama coupling reaction. More stable to electrophilic aromatic
substitution than diphenyldichlorosilane.
Eaborn reported that fluorosilanes are more reactive toward organometallic reagents than the
corresponding chlorosilanes, and therefore more suited for preparation of sterically hindered organosilanes.
Preparation
commercially available. Readily prepared by oxidation of diphenylsilane with CuF2, or by treatment of diphenyldichlorosilane with HF, ZnF2, NaBF4, or (NH4)2SiF6. Rate enhancements of the chlorine–fluorine exchange have been achieved with ultrasound and addition of water. Diethoxydiphenylsilane and related structures are converted to diphenyldifluorosilane with 48% HF(aq).
