Luminescent Pt(ii) complexes bearing dual isoquinolinyl pyrazolates: Fundamentals and applications

A series of four Pt(ii) metal complexes with trans-arranged isoquinolinyl azolates have been prepared, [Pt(Lx)2], x = 1-4, (1-4). The associated chelates possess various substituents; namely: one t-butyl (But) at the 6-position (L1), two But groups at the 5,7-positions (L2), one dip (2,6-di-isopropylphenyl) group at the 6-position (L3), and a single dip group at the 4-position of the 1-isoquinolinyl fragment (L4), respectively. Crystal structures of 1 and 4 were determined to shed light on the relationship of photophysics and packing arrangements. Their photophysical properties were measured and compared, for which the solid-state emission spectra of 2 and 4 are nearly identical to the solution spectra of all the Pt(ii) complexes, showing the formation of isolated molecular entities. In contrast, the Pt(ii) complexes 1 and 3 are found to be sensitive to their morphological states and external stimulus. This is confirmed by the gradual red-shifting of the emission with increasing concentration in the PMMA matrix, and the eventual formation of the broadened, metal-metal-to-ligand charge transfer (MMLCT) emission, by (i) wetting with acetone and drying in air, or (ii) grinding with a mortar and pestle, respectively. Organic light-emitting diodes (OLEDs) were also fabricated using multiple layered architecture and lowered doping concentration (e.g. 8 wt%), the latter is for avoiding dopant aggregation in the emitting layer. The associated OLED performances (i.e. etamax = 11.5%, 8.5%, and 11.2% for 1, 2 and 3) confirmed their suitability and potential as dopants for phosphorescent OLEDs.

Palladium catalyzed direct 3-arylation of benzofurans using low catalyst loadings

The palladium-catalyzed direct 3-arylation of benzofurans provides a cost-effective and environmentally attractive route for the preparation of 3-arylbenzofuran derivatives. The reactions were carried out using a wide variety of electronically and sterically diverse aryl or heteroaryl bromides with low catalyst loadings. In the presence of only 0.1-0.5 mol% catalyst, products in moderate to good yields were obtained. The aryl bromide reactants were able to tolerate a wide range of functionalities, such as acetyl, propionyl, formyl, ester, nitrile, trifluoromethyl, or fluoro groups. Higher yields were obtained using electron-deficient aryl bromides as reactants compared to using electron-rich aryl bromides. Functionalized benzofuran derivatives, bearing formyl or hydroxymethyl on C2, were also successfully employed.

Efficient coupling of heteroaryl halides with arylboronic acids in the presence of a palladium-tetraphosphine catalyst

Cis, cis, cis-1,2,3,4-tetrakis(diphenylphosphinomethyl) cyclopentane: ¡¤1/2[PdCl(C3H5)]2 system catalyses the Suzuki cross-coupling of heteroaryl halides with a range of arylboronic acids with very high ratio substrate/catalyst in good yields. Substrates such as pyridines, quinolines, thiophenes, an indole, pyrimidines or a furane have been used successfully.

Double Hydroboration of Quinolines via Borane Catalysis: Diastereoselective One Pot Synthesis of 3-Hydroxytetrahydroquinolines

Described herein is an organoborane-catalysed consecutive borylative reduction of quinolines and isoquinolines to furnish tetrahydro(iso)quinolines bearing a C(sp3)?B bond beta to the nitrogen atom. The installed C?B bond is oxidatively transformed to the hydroxy group in one pot. The present double hydroboration is proposed to proceed via a stepwise ionic mechanism involving a boronium ion. The stereo-outcome was found to be dependent on the position (C2 vs C4) of the substituents in quinolines. (Figure presented.).

Photo-induced Metal-Catalyst-Free Aromatic Finkelstein Reaction

The facile iodination of aromatic compounds under mild conditions is a great challenge for both organic and medicinal chemistry. Particularly, the synthesis of functionalized aryl iodides by light has long been considered impossible due to their photo-lability, which actually makes aryl iodides popular starting materials in many photo-substitution reactions. Herein, a photo-induced halogen exchange in aryl or vinyl halides has been discovered for the first time. A broad scope of aryl iodides can be prepared in high yields at room temperature under exceptionally mild conditions without any metal or photo-redox catalysts. The presence of a catalytic amount of elemental iodine could promote the reaction significantly.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 55270-33-2

Breaking Symmetry: Engineering Single-Chain Dimeric Streptavidin as Host for Artificial Metalloenzymes

The biotin-streptavidin technology has been extensively exploited to engineer artificial metalloenzymes (ArMs) that catalyze a dozen different reactions. Despite its versatility, the homotetrameric nature of streptavidin (Sav) and the noncooperative binding of biotinylated cofactors impose two limitations on the genetic optimization of ArMs: (i) point mutations are reflected in all four subunits of Sav, and (ii) the noncooperative binding of biotinylated cofactors to Sav may lead to an erosion in the catalytic performance, depending on the cofactor:biotin-binding site ratio. To address these challenges, we report on our efforts to engineer a (monovalent) single-chain dimeric streptavidin (scdSav) as scaffold for Sav-based ArMs. The versatility of scdSav as host protein is highlighted for the asymmetric transfer hydrogenation of prochiral imines using [Cp*Ir(biot-p-L)Cl] as cofactor. By capitalizing on a more precise genetic fine-tuning of the biotin-binding vestibule, unrivaled levels of activity and selectivity were achieved for the reduction of challenging prochiral imines. Comparison of the saturation kinetic data and X-ray structures of [Cp*Ir(biot-p-L)Cl]¡¤scdSav with a structurally related [Cp*Ir(biot-p-L)Cl]¡¤monovalent scdSav highlights the advantages of the presence of a single biotinylated cofactor precisely localized within the biotin-binding vestibule of the monovalent scdSav. The practicality of scdSav-based ArMs was illustrated for the reduction of the salsolidine precursor (500 mM) to afford (R)-salsolidine in 90% ee and >17 ?000 TONs. Monovalent scdSav thus provides a versatile scaffold to evolve more efficient ArMs for in vivo catalysis and large-scale applications.

Synthesis of primary amides by aminocarbonylation of aryl/hetero halides using non-gaseous NH3 and CO sources

Abstract A practically simple method for the synthesis of primary amides via the palladium-catalysed aminocarbonylation of aromatic halides by using solid sources of gaseous ammonia and carbon monoxide is described. The system tolerated a wide variety of hindered and functionalized aryl/hetero halides and afforded good to excellent yields (69-94%) of the amide. Pharmacologically active Exalamide and Pyrazinecarboxamide were synthesised in high yields to demonstrate the effectiveness of this method.

Sterically controlled iodination of arenes via iridium-catalyzed C-H borylation

A mild method to prepare aryl and heteroaryl iodides by sequential C-H borylation and iodination is reported. The regioselectivity of this process is controlled by steric effects on the C-H borylation step and is complementary to existing methods to form aryl iodides. The iodination of boronic esters has potential for the synthesis of radiolabeled aryl iodides, as demonstrated by the concise synthesis of a potential tracer for SPECT imaging.
