• The Diels-Alder reactions of polychlorocyclopentadienes with substituted ethylenes were investigated, and the rates of the reaction and the <I>endo</I> : <I>exo</I> adduct distributions were determined. The introduction of a chlorine atom at the C<SUB>5</SUB> position of cyclopentadiene resulted in an enhanced <I>endo</I> preference for substituents in the adducts, despite the depressed reactivity of the diene. This is contrary to what is to be expected from the so-called "selectivity-reactivity relationship in the Diels-Alder reaction." The results in this work were explained in terms of steric interaction between the C<SUB>5</SUB>-chlorine atom of the diene and the substituent of dienophiles.
