“…Thus, changing to a ligand that would more readily undergo a switch of hapticity was expected to enhance the reactivity in the isomerization of more-difficult substrates. [85] Indeed, the indenyl complex 105 [86][87][88] proved to be much more reactive and afforded the isomerized product 108 in excellent yield in only 2 h [Eq. (28)].…”

The demand for new chemicals spanning the fields of health care to materials science combined with the pressure to produce these substances in an environmentally benign fashion pose great challenges to the synthetic chemical community. The maximization of synthetic efficiency by the conversion of simple building blocks into complex targets remains a fundamental goal. In this context, ruthenium complexes catalyze a number of non-metathesis conversions and allow the rapid assembly of complex molecules with high selectivity and atom economy. These complexes often exhibit unusual reactivity. Careful consideration of the mechanistic underpinnings of the transformations can lead to the design of new reactions and the discovery of new reactivity.

“…Similar to other Ru II indenyl complexes, the Ru-C distances involving the bridging carbon atoms C(25) and C (29) . [25] The pendant ptpy substituent of the indenyl group is significantly twisted and nonplanar with a dihedral angle between the 4-tolyl and pyridyl rings of about 36.8°.…”

Transmetalation of Hg(ptpy)2 [Hptpy = 2‐(4‐tolylpyridine) with Cp*Ru(NO)Cl2 (Cp* = η5‐C5Me5)] gave [Cp*Ru(NO)(ptpy)]2[Hg2Cl6] ([1]2·Hg2Cl6) whereas that with [Cp*RuCl2]x gave the dinuclear RuII–RuIV compound [Cp*Ru(μ‐η6:η2‐ptpy)RuCl2Cp*][Hg2Cl6] (2). Treatment of Ru(3‐phenylindenylid‐1‐ene)Cl2(PPh3)2 with Hg(ptpy)2 resulted in coupling of ptpy with the 3‐phenylidenylid‐1‐ene ligand, and the formation of Ru(Ph‐ind‐ptpy)(PPh3)Cl {Ph‐ind‐tpy = 3‐phenyl‐1‐[2‐(4‐toyl)pyridyl]indenyl} (3), in which the chelated [Ph‐ind‐tpy]– ligand binds to Ru through the η5‐indenyl ring and the pendant pyridyl group. Treatment of [Ru(CO)2Cl2]n with [Hg(ptpy)Cl]2 afforded [Ru(ptpy)(CO)2]2(μ‐Cl)2 (8). Irradiation of cis‐[Ru(bzq)2(CO)2] (Hbzq = benzo[h]quinoline) with UV light in MeCN afforded cis‐[Ru(bzq)2(CO)(MeCN)] (9). Photolysis of cis‐[Ru(bzq)2(CO)2] in THF in the presence of PPh3 and pyridine (py) afforded cis‐[Ru(bzq)2(CO)(L)] [L = PPh3 (10), py (11)]. The crystal structures of complexes 1–3, 8, and 10 have been determined. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)

“…48,7° stark verdreht, so daß minimale sterische Hinderung resultiert. Die strukturellen Eigenschaften der Iridium-IndenylEinheit in 3 weisen ansonsten die auch bei unsubsti tuierten Indenylkomplexen gefundenen Besonder heiten auf [6]. So ist der mittlere A bstand des IrAtoms zu C(51), C(52) und C(53) mit 220,7 pm si gnifikant kürzer als der zu C(21) und C(23) (235,4 pm), d. h. die Position des Ir-A tom s fällt nicht mit der H auptachse des Fünfringes zusammen.…”
