To obtain Diels-Alder adducts with even higher rates of cycloreversion, we synthesized the adduct of benzene with the h side of naphthalene in an analogous way; the precursor was the tetracycle 13. By cycloaddition of anhydride 4 to a stereoisomeric mixture of 8,9-dichlorobicyclo[4.2.0]octadiene 10,

## on the occasion of his 65th hirthday The recently reported successful stabilization of cyclo-As5 and cyclo-P, ("hexaphosphabenzene") as bridge ligand ("middle deck") in the triple-decker complexes l"] and 2") respectively, signaled the possibility of also stabilizing cvclo-P, in the same way.[3
