- R. Hoffmann and co-workers suggested that substitution on thiirane ring by π-acceptor groups would lead to a weaker C-C bond, and hence the thiepin form will be favored in equilibrium with thianorcaradiene form which is thought to be a possible intermediate for thermal sulfur extrusion reaction of the thiepin system.

- We feel that the relatively high stability of (1) can be ascribed in part to the presence of a resonance contributor such as (i) arising from the “push-pull” effect of the adjacent pyrrolidinyl and methoxycarbonyl groups.
