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.

Two novel chloride-centered Ag18 clusters with the same framework but different supporting phosphines are synthesized by the reaction of PhCCAg, AgSbF6, PPh3 (or P(p-Tol)3), and NaBH4 in CH2Cl2, followed by the addition of PhCCH and NEt3. The inner twelve Ag atoms of these two clusters are arranged in a rare cuboctahedral structure, which can be rationalized by considering a ligand effect. Through careful analysis, we find that the central chloride arises from a generally ignored but nonetheless existing reaction between CH2Cl2 and NEt3, which is well recognized as the Menshutkin reaction. This research provides insights into the dependence of the cluster structure on the nature of the ligand and into the cluster formation mechanism of the Menshutkin reaction.

A variety of donor-stabilized cationic complexes of the form [Cp(NPt-Bu3)TiMe(L)][MeB(C6F5)3] and [Cp(NPt-Bu3)TiMe(L)] [B(C6F5)4] (L = Py, 4-EtPy, 4-t-BuPy, NC5H4NMe2, PMe 3, Pn-Bu3, PPh3, P(p-MeC6H 4)3 have been prepared and characterized. Prolonged storage in CH2Cl2 solution resulted in chloride for methyl exchange to afford species of the form [CpTi-(NPt-Bu3)Cl(L)] [B(C6F5)4], [{CpTi(NPt-Bu3)Me} 2(mu-Cl)][B(C6F5)4], and [CpTi(NPt-Bu3)(mu-Cl))2[MeB(C6F 5)3]2. The byproduct salt [(o-MeC 6H4)3PCH2Cl] [B(C6F 5)4] was obtained from reactions employing the sterically demanding donor phosphine P(o-MeC6H4)3, suggesting transient generation of the cation [CpTi(NPt-Bu3) Cl(CH2Cl2)]+. Analogous reactivity was not seen in C6H5Cl, although the species [{CpTi(NPt-Bu 3)Me}2(mu-Me)][B(C6F5) 4] could be formed in this solvent. The isolated zwitterionic complex TiCp(NPt-Bu3)Me(mu-MeB(C6F5)3) readily performs insertion chemistry into the Ti-methyl bonds with diisopropylcarbodiimide and diphenylacetylene substrates to afford the cationic species [CpTi(NPt-Bu3)(Ni-Pr)2CMe)][MeB(C 6F5)3], [TiCp(NPt-Bu3)(PhCCPh(Me))] [MeB(C6F5)3], and [TiCp(NPt-Bu 3)(PhCCPh(Me))(PMe3)][MeB-(C6F 5)3. The implications of this chemistry are considered.

Among the various postsynthesis treatments of colloidal nanocrystals that have been developed to date, transformations by cation exchange have recently emerged as an extremely versatile tool that has given access to a wide variety of materials and nanostructures. One notable example in this direction is represented by partial cation exchange, by which preformed nanocrystals can be either transformed to alloy nanocrystals or to various types of nanoheterostructures possessing core/shell, segmented, or striped architectures. In this review, we provide an up to date overview of the complex colloidal nanostructures that could be prepared so far by cation exchange. At the same time, the review gives an account of the fundamental thermodynamic and kinetic parameters governing these types of reactions, as they are currently understood, and outlines the main open issues and possible future developments in the field.

Two new ternary platinum(II) complexes of general formula [Pt(DTC)LCl], where DTC = 4-(2-pyridyl)piperazine-1-carbodithioate (1 and 2) and L = tri(p-tolyl)phosphine (1) and tri(o-tolyl)phosphine (2), have been synthesized and characterized. Both complexes have shown phenanthriplatin and picoplatin type axial protection, albeit from both sides, offered by C?H moiety of the organophosphine (X-ray single crystal and DFT analysis). Furthermore, 2 has shown greater degree of axial shielding of platinum center than 1. In vitro anticancer activity against three cancer cell lines has revealed greater anticancer potency of 2 than 1. The activity against NF-kappaB (a cancer promoting protein) signified that death of the cancer cells may be due to hindering the activity of NF-kappaB and subsequent initiation of the apoptosis. High activity of 2 than 1 can be attributed to its greater lipophilicity and stronger axial protection (C?H?Pt = 2.752 A H?C?Pt 3.496 A ?H?Pt-P = 78.37 and ? C?Pt-P = 64.19), from both sides of the axial plane, that may hinder the diversion to off target biomolecules and thus may enhance cellular uptake. Based upon DNA binding and DNA denaturing studies with CT-DNA, a cooperative binding and non-intercalative (electrostatic/covalent) mode of interaction have been suggested.

The reaction of aryl nitroso compounds with organic phosphines and phosphites in aerated media is a convenient non-photolytic procedure to generate aromatic nitroso oxides. The reaction rate constants and activation parameters of the key (for the proposed method of nitroso oxide generation) reaction of nitrosobenzene with tripenyl phosphite or para-substituted phosphines (4-RC 6H4)3P (R = MeO, Me, H, F), as well as that of para-methoxynitrosobenzene with triphenylphosphine in acetonitrile were determined by kinetic spectrophotometry and chemiluminescence. A significant transfer of the electron density to the nitroso compound occurs in the transition state of the reaction as was revealed using the Hammett correlation analysis and DFT calculations in the M06L/6-311+G(d,p) approximation. The introduction of the electron-donor substituent MeO into the para-position of PhNO decreases the reactivity of the nitroso compound by two orders of magnitude. The reactivity of triphenyl phosphite in the oxygen atom transfer reaction is lower by two orders of magnitude compared to that of triphenylphosphine. In the case of the reactions of PhNO with phosphines, the apparent rate constant depends on the oxygen content in the reaction medium.

An extended series of phosphines (L), having widely different steric and electronic properties, was used to study the kinetics of chloride substitution on the cyclometallated complex [Pt(N-N-C)Cl] (N-N-CH = 6-(1-methylbenzyl)-2,2?-bipyridine). The final cationic products [Pt(N-N-C)(L)]+ were fully characterised by 1H and 31P{1H} NMR spectroscopy in CDCl3 solution. The values of the 1J(PtP) coupling constants for these complexes showed interesting dependencies upon the size and the sigma-donor ability of the ligands. The reaction, in dichloromethane as solvent at 298.2 K, takes place by way of a direct bimolecular attack of the ligand on the substrate, with no evidence of a significant solvent contribution. The order of reactivity is that expected on the basis of the nucleophilic reactivity constants (nPPt), derived from previous studies. The values of the second-order rate constants (k2, M-1 s-1) can be resolved quantitatively into steric, electronic and aryl contributions of the phosphine ligands, by use of a four-parameter equation k2 = alpha + beta(pKa?) + gamma(theta) + delta(Ear), where pKa? measures the sigmar-donor ability of the phosphines, theta (Tolman’s cone angle) is a measure of the size of the P-donor ligand, and Ear is related to the number of aryl groups attached to the ligand phosphorus atom. This is the first reported example of an aryl effect contributing to the nucleophilicity of phosphines as entering ligands on square-planar complexes. No steric threshold is observed. Steric and electronic profiles for the substitution process can be plotted showing the dependence of rates on the size and the sigma-donor ability of the phosphines. The sensitivity of the rates to pKa? is significant (beta = 0.20 ± 0.04) and this is related to the structural properties of the substrate.
