Perchlorates have been frequently employed to promote a variety of
synthetic transformations under ambient conditions. For example, the
LiClO4-diethyl ether solvent medium has proven to be a powerful substitute
for external high pressure for Diels-Alder reactions and other organic
reactions. In this chapter are discussed several such organic transformations
where perchlorates have played highly significant role in promoting their
rates and yields.
