资源简介：
Re2O7 in hexafluoroisopropyl alcohol provides
access to cationic intermediates from alcohols through the intermediacy
of perrhenate esters. This manuscript describes the application of
the system to the formation of a number of weakly basic heterocyclic
systems through dehydration reactions and intramolecular nucleophilic
addition. The influence of the substrate structure on the reaction
rates and stereocontrol is discussed with respect to intermediate
ion pairs.
