2,5‐Bis(di‐ tert ‐butylfluorosilyl)furan reacts with potassium hydroxide in a 1:2 molar ratio to give 2,5‐bis(di‐ tert ‐butylhydroxysilyl)furan, O(CRCH) 2 [R = SiOH(CMe 3 ) 2 ( 1 )]. Compound 1 is very selective in its adduct formation and forms host‐guest complexes in the presence of KF [ 1· 1/2KF ( 2 )], H 2 O [ 1· H 2 O ( 3 )], NH 3 [ 1· NH 3 ( 4 )] and MeNH 2 [ 1· 2MeNH 2 ( 5 )]. The host‐guest complexes are stable at room temperature. Compound 4 is the first neutral ammonia cage that is stable up to 100 °C. The crystal structures of 2 , 3 , 4 and 5 have been determined.
