摘要
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(CMe3)(2) (1)], Compound I is very selective in its adduct formation and forms host-guest complexes in the presence of KF [1.1/2KF (2)], H2O [1.H2O (3)], NH3 [MeNH3 (4)] and MeNH2 [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 degreesC. The crystal structures of 2, 3, 4 and 5 have been determined.
