Carbon-rich ruthenium allenylidene complexes bearing either a hexaarylbenzene (HAB) or a hexa-peri-hexabenzocoronene (HBC) substituent were synthesised. This was achieved via the corresponding propargyl alcohols with HAB and HBC substituents, which were accessible via 3 or 4 step reaction cascades. Reaction of the propargyl alcohols HC[triple bond, length as m-dash]C(OH)Ph(HAB) and HC[triple bond, length as m-dash]C(OH)Ph(HBC) with [RuCl(η5-C5H5)(PPh3)2] yielded the complexes [Ru(η5-C5H5)([double bond, length as m-dash]C[double bond, length as m-dash]C[double bond, length as m-dash]C(HAB)(Ph))(PPh3)2]PF6 and [Ru(η5-C5H5)([double bond, length as m-dash]C[double bond, length as m-dash]C[double bond, length as m-dash]C(HBC)(Ph))(PPh3)2]PF6. The latter of which shows interesting π-π-stacking behaviour in the solid state as well as aggregation in solution.
合成了带有六芳基苯（HAB）或六并六苯（HBC）取代基的富碳钌亚丙二烯基配合物。这是通过相应的带有HAB和HBC取代基的炔丙醇实现的，这些炔丙醇可通过3步或4步反应级联获得。炔丙醇HC≡C(OH)Ph(HAB)和HC≡C(OH)Ph(HBC)与[RuCl(η5-C5H5)(PPh3)2]反应，生成配合物[Ru(η5-C5H5)(═C═C═C(HAB)(Ph))(PPh3)2]PF6和[Ru(η5-C5H5)(═C═C═C(HBC)(Ph))(PPh3)2]PF6。后者在固态时表现出有趣的π-π堆积行为，在溶液中也会聚集。
