Ruthenium(II) complexes of formula [Ru(?6-arene)Cl2(PTA)] (RAPTA) are potential anticancer drugs with notable antimetastatic and antiangiogenic activity, which are now pointing to clinical trials. Following the great interest aroused by these compounds, a variety of RAPTA derivatives, obtained by chloride substitution and/or containing functionalized arene ligands, and complexes resembling the RAPTA structure but bearing different phosphorous ligands have been synthesized and evaluated for their anticancer activity. An overview of all of these biologically relevant complexes will be given, with particular reference to the anticancer behaviour exhibited by the compounds and the possible relationship with structural aspects.

The synthesis and characterization of a series of platinum and palladium complexes containing a secondary borane Z-class ligand supported by 2-mercaptopyridine heterocycles is reported herein. Addition of 2 equiv of Na[H2B(mp)2] to [Pt(mu-Cl)(COEOMe)]2 (where COEOMe = 8-methoxycyclooct-4-en-1-ide) in the presence of 2 equiv of a tertiary phosphine (PR3 = PPh3, PCy3, PCyp3, P(o-tol)3, PPh2(o-tol), PPh2(2-(3-methyl)indolyl)) leads to the formation of the complexes [Pt{kappa3-S,B,S-HB(mp)2}(PR3)] (1-6). Addition of 2 equiv of Na[H2B(mp)2] to [Pd(mu-Cl)(COEOMe)]2 in the presence of 2 equiv of a tertiary phosphine (PR3 = PPh3, PCy3, PCyp3, PPh2(o-tol)) leads to the formation of the complexes [Pd{kappa3-S,B,S-HB(mp)2}(PR3)] (7-10). It was also demonstrated that the synthesis of the palladium complex 7 could be achieved from the palladium precursor [PdCl(Me)(COD)] (where COD = 1,5-cyclooctadiene) as an alternative synthetic strategy. In the above reactions, either the COEOMe fragment or the methyl fragment serves to act as a “hydride acceptor” facilitating the ultimate transformation of the borohydride-based ligand [H2B(mp)2]- to the corresponding secondary borane kappa3-S,B,S coordinated HB(mp)2 pincer ligand. The complexes [Pd{kappa3-S,B,S-HB(mp)2}(PR3)] and [Pt{kappa3-S,B,S-HB(mp)2}(PR3)] are rare examples of metal-borane complexes where one hydrogen substituent remains at the boron center. These compounds have particularly short palladium- and platinum-boron distances, the shortest of the structurally characterized compounds being 2.067(6) A for [Pd{kappa3-S,B,S-HB(mp)2}(PPh2(o-tol))] and 2.076(10) A for [Pt{kappa3-S,B,S-HB(mp)2}(PCy3)], respectively (the shorter distances of two independent complexes in the unit cells of both structures).

Narrow bandgap and hyperbranched polymers (h-PTDPP) are synthesized by directly arylation polymerization (DAP) of 2-bromo-thiophene-flanked diketopyrrolopyrrole (Br-TDPP) as the monomer. Their optical properties as well as chemical structures are studied. The detailed optimization of DAP conditions from catalyst, temperature, solvent, ligand to additive not only leads to high molecular weight h-PTDPP, but also provides some insight to minimize structural defects in DAP when brominated TDPP is involved as a monomer. The increase in the degree of branching results in lower charge-carrier mobilities in organic field-effect transistors involving h-PTDPP-3 as the semiconducting channel.

A bidentate phthalaldehyde ligand with both sigma and pi coordination of the aldehyde groups is found in [(C5Me5)Co{(C(O)H)2C6H4}] (structure depicted). This complex is the ‘resting state’ of the catalyst in the ring closure of the dialdehyde to give the lactone. Interchange of coordination modes occurs with a barrier of 70 kJ mol-1 at 35C. Investigation of other Co1 chelate complexes with a single aldehyde group shows that the coordination mode of the aldehyde is dictated by the nature of the bonding of the other ligating group.

Isomerisation of allylic alcohols forms an elegant shortcut to carbonyl compounds in a completely atom-economical process that offers several useful applications in natural-product synthesis and in bulk chemical processes. This review focuses on the heart of isomerisation catalysis: the catalyst. Combinations of transition metals (from Group 4 to 10), ligands and reaction conditions are compared with respect to yield, turnovers, rate and selectivity. A selected number of clever solutions to synthetic problems are highlighted, such as the synthesis of enols and enolates, chiral carbonyl compounds and silyl substituted ketones. Furthermore, a general overview of the of the mechanisms proposed for the isomerisation of allylic alcohols is given while some catalyst systems are singled out to discuss mechanistic research.

A carbonylative alpha-arylation process employing unactivated nitriles for the first time is described. The reaction tolerates a range of (hetero)aryl iodides and several nitrile coupling partners. No prefunctionalization of the nitriles is necessary and the resulting beta-ketonitriles are obtained in good to excellent yields. The methodology also allows for a convenient 13C-labelling of the generated carbonyl moiety.

Lithium-ion batteries (LIBs) have become one of the most prevalent techniques for feasible and fascinating energy storage devices used in portable electronics and electric vehicles; however, they still face a significant challenge due to the complicated electrode-electrolyte interface (EEI), which is closely related to the chemical/electrochemical instability of high-capacity high-voltage electrodes and electrolytes. In particular, the decomposition of an electrolyte on the electrode surface is unambiguously regarded as a crucial controlling factor for the obtainable capacity, rate capacity, and interfacial chemistries of batteries. Previously, significant efforts have been devoted toward modifying the EEI with remarkable progress. The incorporation of a small dose of foreign molecules, called film-forming additives, is regarded as one of the most economical and effective approaches to circumvent these predicaments. In this regard, this review provides an overview of various film-forming additives used for classified anodes and cathodes, aiming at emphasizing the state-of-the-art developments in the electrolyte research. Moreover, the authors intend to help the readers arouse new ideas and easily identify the additives suitable for their target materials, paving the way for greater progress in the lithium-ion battery community.
