Abstract
The Diels-Alder reaction of cyclopentadiene with methyl vinyl ketone was re markably promoted by anhydrous LiTFPB as a Lewis acid catalyst both in dich loromethane and in toluene. Experimental and computational investigations r evealed the effects of solvent, hydrating water molecules, and counter anio ns on the Lewis acidity of the "naked" lithium ion.
