✦ Synopsis

Abstract

The title compounds have been isolated and their structures determined by X‐ray crystallography. Their relative stability is discussed in terms of theory and experiment. The endo‐adduct is the thermodynamically more stable one.

## Abstract Relatively few __exo__‐adducts have been obtained from the title compounds. Only one such mono‐adduct, **3**, is known. Several __exo‐endo__‐bis‐adducts have been obtained but the structure of one of these, **5**, has been proved unequivocally by X‐ray structural determination.
