The stereoselectivities of electrophilic additions to acyclicallylicalcohols with and without internalnucleophiles have been assessed with use of previously developed chemical reactivity modeling techniques. Reactions normally assumed to proceed via onium-type intermediates have been investigated. The diastereofacial selectivity of attack by I/sub 2/, Br/sub 2/, PhSeCl, Hg(OAc)/sub 2/, and related
