F-19, B-11, and Si-29 NMR spectroscopy was used to examine the behavior of the guest-host complexes (BF3.H2O)(2). 18-crown-6 . 2H(2)O, (BF3.H2O)(2). DCH-6B, and (DCH-6A .H3O)SiF5 in acetone (DCH-6B and DCH-6A are the cis-anti-cis- and cis-syn-cis-isomers of dicyclohexano- 18-crown-6, respectively). It was shown that molecular boron fluoride complexes undergo partial solvolysis in acetone to yield BF3. acetone as the main product; the ionic pentafluorosilicate complex does not experience significant solvolysis transformations.
