✦ Synopsis

The photochemistry of solid complexes of large ring 2-phenylcycloalkanones adsorbed in cyclodextrin cavities results in significant yields of enals as disproportionation products, at the expense of the pararearrangement, depending on both the ring size of the cyclanone and the cavity size of the cyclodextrin. This behavior

contrasts with its photoreaction in homogeneous solutions which yields predominantly para-cyclophanes.
