All roads lead to Rome and to the heterometallacycle [Cp 2 M(κ 2 ‐ P , P ‐Ph 2 P‐N‐PPh 2 )]. In their Communication on page 10546 ff. , U. Rosenthal, T. Beweries et al. describe four different, yet straightforward ways of synthesizing unusual four‐membered metallacycles of Group 4 metallocenes based on a bis(diphenyl)amide ligand framework. The cover picture shows a drawing of the Colosseum as a metaphor for the metallacyclic product complex and roman roads symbolizing the synthetic pathways leading to it.
