45- 189 Episelenonium
(I) bearing an arylseleno group on the adjacent carbon atom with Lewis acid forms chiral episelenonium ions. The latter undergo intermolecular nucleophilic substitution
with various aromatic compounds to give the corresponding substituted products selectively. The only exception is observed in the case of substrate (VI). — (OKAMOTO,
