Hydrofluoric Acid → Chloromethyl(fluoro)[bis(4-fluorophenyl)]silane

Participants

Reaction Steps

A solution of 11.0 g (33.7 mmol) of chloromethyl[bis(4-fluorophenyl)](2-propoxy)silane and 10 ml of 49% aqueous hydrofluoric acid in ethanol was refluxed for 2 hours under nitrogen, cooled, and partitioned between water and ether. The organic layer was washed with water and brine, dried over magnesium sulfate, and evaporated to leave 9.7 g (100%) of chloromethyl(fluoro)[bis(4-fluorophenyl)]silane as a mobile oil: nD22 1.5387; nmr (CDCl3) 3.2 (2H, d), 7.2 (4H, t), 7.8 (4H, d of d).
