title: Investigations into the role of ion pairing in reactions of heteroatom-substituted cyclic oxocarbenium ions.
abstract: [reaction: see text] The O-to-C rearrangement of vinyl acetals is used to demonstrate that tight ion pairing is not involved in the stereoselective nucleophilic addition reactions of alkoxy-substituted cyclic oxocarbenium ions.
