Gas driven : A high‐yield approach to sequential fluoride ion abstraction from SbF 3 in the presence of 2,2′‐bipyridine gives a series of complexes containing [SbF 2 ] + , [SbF] 2+ , and [Sb] 3+ (see figure) acceptors. The thermodynamically favorable rapid elimination of gaseous Me 3 SiF provides a potentially general approach to enhance the Lewis acidity and coordination chemistry of p‐block centers.
