Direct access to trideuteriomethoxylated aromatic and heteroaromatic compounds has been developed. Various aryl and heteroaryl halides underwent d3-methoxylation under mild reaction conditions by using a catalyst system composed of the commercially available monodentate phosphane ligand tBuXPhos and Pd(OAc)2. Inexpensive CD3OD served as an efficient trideuteriomethoxylating agent. The simple and straightforward synthesis of labeled methyl (hetero)aryl ethers via palladium-catalyzed C-O cross-coupling reaction of (hetero)aryl halides with CD3OD was developed. The tBuXPhos ligand is used for the first time in ether synthesis. Copyright

A practical approach for the synthesis of phosphinic amides via the coupling of secondary phosphine oxides (SPOs) with O-benzoylhydroxylamines has been reported. Simply heating the mixture of SPOs and O-benzoylhydroxylamines in the presence of K2CO3 gave the phosphinic amides in moderate to excellent yields under an open air system. This method provides a practical and catalyst-free method for the synthesis of various synthetically valuable phosphinic amides.

A rhodium-catalyzed system is introduced for in situ modification of biaryl-type monophosphines with hydrosilanes through a PIII-chelation-assisted dehydrogenative silylation reaction. A series of ligands containing silyl groups with different steric and electronic properties were obtained with excellent regioselectivities. This method offers many advantages, including the use of commercially available phosphines, no requirement for an external ligand or oxidant, a broader substrate scope, high efficiency, and access to a single regioisomer. Based on the outstanding properties of the parent scaffolds, the silyl-substituted phosphines serve as excellent ligands in Pd-catalyzed asymmetric Suzuki coupling reactions.

Organic light-emitting diodes (OLEDs) are currently being commercialized for lighting and display applications, but more work has to be done. In addition to the ongoing optimization of materials and devices in terms of efficiency and lifetime, the substitution of processing steps involving vacuum deposition for solution processing techniques is favorable. To reach this aim, good soluble materials are required. A modular family of highly emissive PyrPHOS-copper iodide complexes featuring various ancillary phosphine ligands has been synthesized. Photoluminescence spectroscopy, TCSPC (time-correlated single photon counting), cyclic voltammetry, X-ray diffraction, and DFT calculations were performed to gain a broad understanding of the complexes. While the photophysical properties are consistent within the family, thermal stability and solubility depend on the ligands. The materials showed very high photoluminescence quantum efficiencies up to 99% in powders and 85% in thin films. Selected examples were tested in devices, confirming the suitability of heteroleptic PyrPHOS-complexes for OLEDs.

Ru-catalyzed directed o-C?H arylation reactions of 2-phenylpyridine, N-phenylpyrazole, acetophenone N-(p-methoxyphenyl)imine, and 2-phenyloxazoline proceed in good to excellent yields with a number of functionalized aryl and heteroaryl bromides in neat Bu4NOAc at 120 C. The acetate ion acts as the base and the relatively low melting point Bu4N salts (a mixture of acetate and bromide) behave as an ionic liquid. Arylation reactions of 2-phenyloxazoline proceed with concomitant oxazolidine cleavage to give 2-(N-acetylamino)ethyl benzoates promoted by side product CH3COOH. The dual-purpose ionic liquid medium is compatible with both ligandless Ru for di-arylation (optimal pre-catalyst: RuCl3·xH2O) and Ru-phosphane (optimal pre-catalyst: [RuCl2(p-cymene)]2/P(p-Tol)3 1:4) catalysts (1?5 mol-%) for selective mono-arylation.

An NCN pincer palladium complex was developed as a probe molecule to index the coordination ability of various monodentate ligands. Coordination constants of 27 monodentate ligands (L) with a pincer palladium complex to form complexes of the type ArPd(L)2Cl were determined by 1H NMR spectroscopy. This allowed the coordination ability of a wide variety of ligands, including P-coordinating ligands (phosphane, phosphite), as well as As-coordinating AsPh3, and N-coordinating pyridine, to be indexed. The differential between the highest/lowest coordination constants was 10 12. The relative coordination ability is described in a logarithmic manner, log(Keq(L)/Keq(PPh3)), with respect to the value of PPh3 to exhibit high linearity in the Hammett plot.

Coupling of protected or non-protected D-glucosamine with o- or p-(diphenylphosphino)benzoic acid generates carbohydrate-substituted phosphines in quite good yields. The catalytic performance of these new neutral ligands is demonstrated in the Suzuki cross-coupling reaction. The polyhydroxy phosphines are more active than the peracetylated phosphines, and the process tolerates electron-rich as well as electron-poor substituents. Excellent turnovers are observed, and the catalyst can be recycled.
