Palladium-catalyzed heteroaryl thioethers synthesis overcoming palladium dithiolate resting states inertness: Practical road to sulfones and NH-sulfoximines

We provide efficient synthetic access to heteroaryl sulfones in two-steps using a simple palladium?1,1?-bis[(diphenyl)phosphanyl]ferrocene catalyst to form in high yields variously functionalized heteroaromatic thioethers. Pyridinyl-containing substrates can be subsequently selectively oxidized into sulfones and NH-sulfoximines by using very mild oxidation conditions with a high functional group tolerance. In the palladium-catalyzed C?S coupling of heteroaromatic thiols, reactivity limitation is attached with electron-deficient thiols. We show that this limitation can be resolved by the successful use of 2-bromoheteroarenes in the C?S coupling. We established herein that this choice of heteroaryl electrophilic reagent in palladium-catalyzed C?S bond formation allows overcoming palladium dithiolate out-of-cycle resting state inertness. This was illustrated in the stoichiometric reactivity study of the palladium dithiolate formed from 4-trifluoromethylbenzen-1-thiol ?isolated and characterized by multinuclear NMR and XRD? with both 2-chloropyridine and 2-bromopyridine.

Cyclometallated, bis-terdentate iridium complexes as linearly expandable cores for the construction of multimetallic assemblies

Cyclometallated iridium complexes comprised of two terdentate cyclometallating ligands, of the form [Ir(NCN)(NNC)]+, have been explored for the preparation of multimetallic systems by palladium-catalysed cross-coupling reactions. An NNC-coordinating ligand carrying a boronate ester group has been prepared and complexed to iridium to give a boronic acid appended complex of this type, 3. This complex has been subjected to cross-coupling with a bromo-substituted bis-terpyridyl iridium complex to give a dinuclear iridium compound 6, in which one of the two iridium centres is N6-coordinated and the other has an N4C2-coordination sphere. Meanwhile, a bromo-substituted complex 4 has been coupled with a boronic acid-appended ruthenium complex, to give a dinuclear heterometallic complex 8 that can be activated to a second coupling by in situ bromination, offering access to a linear Ir-Ir-Ru trimetallic assembly 11. The electrochemical and luminescence properties of these systems are investigated. In the case of 8 and 11, the behaviour can be rationalised in terms of a supramolecular description: efficient energy transfer occurs from the Ir terminus to the Ru. In contrast, for compound 6, an excited state with significant bridge character appears to play a key role in determining the emission properties. The Royal Society of Chemistry 2009.

Optimizing the conjugation between N,N0-dicarbazolyl-3, 5-benzene and triphenylphosphine oxide as bipolar hybrids for highly efficient blue and single emissive layer white phosphorescent OLEDs

Two bipolar host materials, mCPpPO and mCPmPO have been synthesized by Ni(II)/Zncatalyzed cross-coupling of diphenylphosphine oxide and corresponding aryl bromide. The photophysical properties, HOMO/LUMO orbital distribution and triplet levels of these host materials are investigated and optimized by tuning the linking modes between electron acceptor triphenylphosphine oxide and electron donor N,N0-dicarbazolyl-3,5-benzene (mCP). When mCP is linked to the meta-position of benzene of triphenylphosphine oxide, the hybrid (mCPmPO) shows much higher steric hinderance than the para-position linked analogue (mCPpPO) so that it possesses a higher triplet energy. Equipped with the bipolar transport properties, mCPmPO-based blue PhOLED doped FIrpic shows a maximum current efficiency (etac,max) of 40.0 cd/A, a maximum power efficiency (etap,max) of 39.7 lm/W, corresponding the maximum external quantum efficiency (etaEQE,max) of 20.3%, and the current efficiency still maintain to 34.8 cd/A even at 1000 cd/m2. Based on the optimized triplet energy level, the single emission layer white PhOLED hosted by mCPmPO shows etac,max, etap,max and etaEQE,max of 46.9 cd/A, 39.7 lm/W and 17.6%, respectively.

Synthesis and properties of dinuclear Ru(II)/Os(II) complexes based on a heteroditopic phenanthroline-terpyridine bridging ligand

The synthesis and characterization of a series of mono- and dinuclear ruthenium(II) and osmium(II) polypyridyl complexes based on the heteroditopic bridging ligand PT are reported. This ligand incorporates bidentate phen (1,10-phenanthroline) and terdentate tpy (2,2?:6?,2?- terpyridine) units directly connected by their 3 and 5 positions, respectively. The dinuclear complexes have been synthesized via a Pd(0) catalyzed cross-coupling reaction between a bromo-substituted Ru-phen complex and a tpy derivative incorporating a boronate ester, followed by Ru(II) or Os(II) complexation. The compounds obtained are fully characterized using spectroscopic and electrochemical measurements. The electrochemical studies do not yield any evidence for interaction between the two metal centers in the dinuclear compounds. Emission studies indicate, however, energy transfer from the phen moiety to the tpy center. For the ruthenium/osmium species, this process is relatively slow, resulting in a dual emission. The emission of the mononuclear ruthenium compound is enhanced by the addition of Zn(II).

Nonsymmetrical 3,4-dithienylmaleimides by cross-coupling reactions with indium organometallics: Synthesis and photochemical studies

The synthesis and photochemical study of novel nonsymmetrical 1,2-dithienylethenes (DTEs) with a maleimide bridge have been carried out. The synthetic approach to the DTEs was based on successive selective palladium-catalyzed cross-coupling reactions of 5-susbtituted-2-methyl-3-thiophenyl indium reagents with 3,4-dichloromaleimides. The required organoindium reagents were prepared from 2-methyl-3,5-dibromothiophene by a selective (C-5) coupling reaction with triorganoindium compounds (R3In) and subsequent metal-halogen exchange. The coupling reactions usually gave good yields and have a high atom economy with substoichiometric amounts of R3In. The results of photochemical studies show that these novel dithienylmaleimides undergo a photocyclization reaction upon irradiation in the UV region and a photocycloreversion after excitation in the visible region, thus they can be used as photochemical switches. ON-OFF operations can be repeated in successive cycles without appreciable loss of effectiveness in the process.

Controlling electron transfer in donor-bridge-acceptor molecules using cross-conjugated bridges

Photoinitiated charge separation (CS) and recombination (CR) in a series of donor-bridge-acceptor (D-B-A) molecules with cross-conjugated, linearly conjugated, and saturated bridges have been compared and contrasted using time-resolved spectroscopy. The photoexcited charge transfer state of 3,5-dimethyl-4-(9-anthracenyl)julolidine (DMJ-An) is the donor, and naphthalene-1,8:4,5-bis(dicarboximide) (NI) is the acceptor in all cases, along with 1,1-diphenylethene, trans-stilbene, diphenylmethane, and xanthone bridges. Photoinitiated CS through the cross-conjugated 1,1-diphenylethene bridge is about 30 times slower than through its linearly conjugated trans-stilbene counterpart and is comparable to that observed through the diphenylmethane bridge. This result implies that cross-conjugation strongly decreases the pi orbital contribution to the donor-acceptor electronic coupling so that electron transfer most likely uses the bridge sigma system as its primary CS pathway. In contrast, the CS rate through the cross-conjugated xanthone bridge is comparable to that observed through the linearly conjugated trans-stilbene bridge. Molecular conductance calculations on these bridges show that cross-conjugation results in quantum interference effects that greatly alter the through-bridge donor-acceptor electronic coupling as a function of charge injection energy. These calculations display trends that agree well with the observed trends in the electron transfer rates.
