The first Dewar benzene-ferrocene conjugates were synthesised by the reaction of tetraalkylcyclobutadiene-AlCl(3) complexes with 3-ferrocenylpropynoates. Owing to extensive delocalisation, these conjugates feature unusually high thermal and chemical stability, rearranging to their corresponding phenylferrocenes (benzenes) under forcing microwave irradiation conditions.
