Both [2+2] and [2+4] additions of inert aromatics via identical ternary host–guest complexes

Abstract

A self-assembled coordination cage enables inert aromatics to undergo both [2+2] and [2+4] cycloadditions by encapsulating them within the cavity. Aceanthrylene reacts with a maleimide derivative under thermal and photo-irradiation conditions to give a product as a single regio- and stereoisomer.
