“…Ruthenaindenes are a subset of ruthenacyclopentadienes that have very few occurrences in the literature . Despite the relative rarity of ruthenaindene-type complexes, there are examples of metalloindenes among the early transition metals such as titanium, vanadium, zirconium, and tantalum, as well as late transition metals including rhodium, osmium, and iridium …”

A series of ruthenaindene complexes containing electron-donating and -withdrawing groups were synthesized and characterized. The ruthenaindenes were synthesized from ruthenium butenynyl complexes which were formed by the treatment of Me 2 Ru(PMe 3 ) 4 with 1,4-diaryl-1,3-butadiynes in methanol. Electrochemistry of the metal center in ruthenaindenes showed that the complexes with electron-donating groups on the aromatic ring have significantly lower oxidation potentials in comparison to complexes with electron-withdrawing groups. Even though the substitution of the aromatic ring with electrondonating/-withdrawing groups is remote from the metal center, the electronic properties of the substituents are relayed effectively to the metal center, indicating that the metal center in the ruthenaindenes is quite intimately embedded into the organic aromatic framework.

The regiocontrol in constructing benzo-fused five-membered rings by C−H cyclization remains an important challenge. We report a highly general and regioselective methodology to access such heterocycles and indenones, where under the catalysis of CoBr 2 /bipyridine, aryl titanates, alkynes and EX 2 (E = NR, S(O), RP(O), R 2 Si, CO, etc.) were assembled to various heterocycles and indenones in a modular manner. Unprecedented 1,2-Co/Ti heterobimetallic arylene and benzotitanole intermediates have played crucial roles in these syntheses.
