To bind or not to bind: Driven by the motivation to increase the (photo)stability of traditional Cu(I) photosensitizers, multidentate diimine ligands, which contain two additional donor sites, were designed. To this end, a systematic series of four 1,10-phenanthroline ligands with either OR or SR (R = iPr or Ph) donor groups at the 2 and 9 positions and their resulting hetero- and homoleptic Cu(I) complexes were prepared. In addition, the related Ru(II) complexes were also synthesized to study the effect of another metal center. In the following, a combination of NMR spectroscopy and X-ray analysis was used to evaluate the impact of the additional donor moieties on the coordination behavior. Most remarkably, for the homoleptic bis(diimine)copper(I) complexes, a pentacoordinated copper center, corresponding to a (4 + 1)-fold coordination mode, was found in the solid state. This additional binding is the first indication that the extra donor might also occupy a free coordination site in the excited-state complex, modifying the nature of the excited states and their respective deactivation processes. Therefore, the electrochemical and photophysical properties of all novel complexes (in total 13) were studied in detail to assess the potential of these photosensitizers for future applications within solar energy conversion schemes. Finally, the photostabilities and a potential degradation mechanism were analyzed for representative samples.

An efficient iridium-catalyzed dehydrogenation, ring-closure reaction, has been developed via a cascade sequence, in which [Cp?IrI2]2/Xantphos proved to be the most efficient catalyst for the synthesis of 2,4,6-triaryl-1,3,5-triazines from stable aryl-substituted alcohols and amidines. It was the first case of iridium catalyst successful application in such transformation.

The reactions of diorganotin(IV) dichlorides SnR2Cl2 (R = Me, n-Bu) with a series of ligands having N, P, or O donor atoms have been investigated. The reaction of SnR2Cl2 (R = Me, n-Bu) with the bidentate chelating pyridyl ligands of phendione (1,10-phenanthroline-5,6- dione) and ndppz (11-nitrodipyrido[3,2-a: 20,30-c]phenazine) affords new hexa-coordinated 1:1 adducts with general formula SnR2Cl2L (R = Me, n-Bu; L = phendione, ndppz). On the other hand, SnMe2Cl2 reacted with xantphos [9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene] to yield the hexa-coordinated 1:2 adduct [SnMe2Cl2 (xantphos)2] in the solid state. However, it dissociates in solution to give the penta-coordinated 1:1 complex [SnMe2 Cl2(xantphos)]. Notably, the analogous n-Bu derivative does not react, even under forcing conditions. Finally, the tin(IV) compounds SnR2Cl2 (R = Me, n-Bu) react with dppap [2-(diphenylphosphinoamino)pyridine] to give the penta-coordinated 1:1 adducts [SnR2Cl2(dppap)] (R = Me, n-Bu). The resulting complexes have been characterized by nuclear magnetic resonance (NMR) spectroscopy and elemental analysis. The X-ray crystal structure determination of [SnMe2Cl2(phendione)] reveals that the compound crystallized with two independent molecules in the asymmetric unit with a trans-[SnMe2] configuration.

Two new iridium (III) complexes (Ir1-Ir2) bearing different fluorinated 2-(biphenyl-4-yl)-2H-indazole-based compounds as cyclometalated ligands and Xantphos as an ancillary ligand were synthesized and fully characterized. The ultraviolet (UV)?vis absorption, photoluminescence, and electrochemistry properties were studied. The single crystal structures of Ir1-Ir2 were determined by X-ray diffraction, showing each adopts the distorted octahedral coordination geometry. To gain insights into the lowest energy electron transitions and the lowest triplet excited states, density functional theory calculations were used to further investigate the origination. Two complexes emit yellow photoluminescence with quantum yields of 49.7?72.5% in solution at room temperature. Their Commission Internationale de L’Eclairage color coordinates are (0.42, 0.53) and (0.39, 0.47), respectively.

The catalyst system for tandem hydroformylation/hydrogenation of terminal alkenes to the corresponding homologated normal alcohol was developed. The reaction mechanism for the Rh/Ru dual catalyst was investigated by real-time IR monitoring experiments and 31P NMR spectroscopy, which proved the mutual orthogonality of Rh-catalyzed hydroformylation and Ru-catalyzed hydrogenation. Detailed investigation about Ru-catalyzed hydrogenation of undecanal under H2/CO pressure clarified different kinetics from the hydrogenation under H2 and gave a clue to design more active hydrogenation catalysts under H2/CO atmosphere. The solely Ru-catalyzed normal selective hydroformylation/hydrogenation is also reported.

For the first time, the monoalkoxycarbonylation of easily available 1,3-diynes to give synthetically useful conjugated enynes has been realized. Key to success was the design and utilization of the new ligand 2,2?-bis(tert-butyl(pyridin-2-yl)phosphanyl)-1,1?-binaphthalene (Neolephos), which permits the palladium-catalyzed selective carbonylation under mild conditions, providing a general preparation of functionalized 1,3-enynes in good-to-high yields with excellent chemoselectivities. Synthetic applications that showcase the possibilities of this novel methodology include an efficient one-pot synthesis of 4-aryl-4H-pyrans as well as the rapid construction of various heterocyclic, bicyclic, and polycyclic compounds.
