## Abstract Reactions of __o__‐(HSiR~2~)(BMes~2~)C~6~H~4~ (R = Me (3a), Ph (3b)) with a fluoride ion afford [__o__‐(FSiR~2~)(HBMes~2~)C~6~H~4~]^−^ (R = Me (5a), Ph (5b)), which involve the FSi⋅⋅⋅HB interaction to render the silicon atom pentacoordinate. The FSi⋅⋅⋅HB interaction in 5a was confir
