The basis for the high selectivity toward the [2 + 2] process is presently not obvious but is being explored computationally.

note
-
The similarity of results with dienes 4 and 10 implies that possible stereoelectronic effects associated with spiroconjugation in 4 have no significant influence on the cycloaddition reactions.

Whether or not the cycloaddition reactions involving free cyclopentyne are diffusion-controlled will be addressed in a subsequent publication.

20 They indeed proposed such a complex but had no evidence for its existence and certainly did not uncover different reactivities for free and a possibly complexed species.
