Summary: A facile synthesis was presented for unprecedented stibastannene (10) with a Sn=Sb double bond, together with homologous arsa- (9) and phosphastannenes (8). The pnictastannenes were obtained by chloride abstraction from respective stannyl pnictinidenes [E=P (5), As (6), Sb (7)] that were accessible via reduction of ECl3 addition products. The pnictastannenes could coordinate Pd(PPh3)(2) fragments (12-14) and the phosphastannene also formed a nickel coordination compound with the Ni(PPh3)(2)-fragment (11). 2,3-Dimethylbutadiene showed a [2+4]-cycloaddition (15-17) with the pnictastannenes (8-10), while phosphaalkyne reaction products (18, 19) were obtained for 8 and 9. Reaction of water with phosphastannene 8 resulted in the addition of an O-H bond at the Sn=P bond. Reaction with ammonia led to NH3-adducts (21-23) at the tin atom for pnictastannenes 8-10, and an azide reaction product featuring a three-membered Sn-As-N ring was obtained for the arsastannene.

Summary: The study investigated the kinetics of reactions between [Ni(bipy)(COD)] and various bicyclopropylidene compounds using stopped-flow techniques. Results supported an associative mechanism and allowed for a more general reaction pathway to be postulated. The structurally characterized nickel(0) and copper(I) complexes exhibited reactivity towards dioxygen, and comparisons were made with similar olefinic complexes in the literature.

Summary: Recent research has focused on the synthesis, structures, and reactivities of N-heterocyclic carbene-coordinated boranes. A synthetic method to access NHC center dot BH2NH2 was developed, and its reactivity with HCl or HOTf was investigated. The introduction of NHC molecules had a significant impact on the solubility and reactivities of aminoboranes.

Summary: This study reports the synthesis of Ni(II) and Pd(II) coordination complexes containing Schiff's bases derived from condensation reactions. The unexpected C-P bond formation during the synthesis process is proposed to occur through a Kabachnik-Field mechanism. The metal complexes were found to act as catalysts in Suzuki-Miyaura couplings, with the Pd(II) derivatives showing better catalytic activity compared to the Ni(II) analogues.

Summary: Tripodal tris(siloxide) ligand supported rare-earth metal complexes LLn(iii) (Ln = Ce, Pr, Tb, Y, Lu) were synthesized. The Ce(iii) complex was oxidized to Ce(iv) chloride complex and then reacted with tBuONa to form a Ce(iv) tert-butoxide complex, both of which showed substantial stability.

Summary: This article reviews the recent progress in the chemistry of two chromium carbonyl pnictogen complexes, which exhibit unique color changes in organic solvents and high affinities towards various nucleophiles. Additionally, a series of heterometallic complexes were produced and the trigonal-planar complexes exhibited semiconductor properties with efficient electron transport. The detailed interactions were studied using DFT calculations.

Summary: The syntheses and structural analyses of representative pyrazolonatocomplexes of main group, transition metal, lanthanide, and actinide elements are discussed. Acylpyrazolone salts and their complexes were synthesized and characterized using single-crystal X-ray crystallography, NMR, and IR spectroscopy. The complexes exhibit diverse coordination arrangements, including (distorted) octahedral, pentagonal-bipyramidal, or antiprismatic structures. Some complexes were found to be polymeric, and their stability was analyzed using TG/DTA measurements. The easily synthesized acylpyrazoloneligands show potential applications in analytical and metal organic framework chemistry.

Summary: This research aims to investigate how changing the metal center from nickel to palladium affects the outcome of CO2 reduction. The results show that palladium hydride complexes react rapidly with CO2 to form palladium formate complexes, which can lose CO2 under reduced pressure or in chloroform. In the presence of HBcat, the formate complexes are converted back to palladium hydride species while the formate group is reduced to CH(3)OBcat. These reactions play a significant role in the catalytic reduction of CO2 with the borane.

Summary: The ruthenium carbene pincer complex 2 was synthesized by treating benzo annulated cycloheptatriene bisphosphine 1 with RuCl3. Addition of three equivalents of hydrogen to generate hydrogenated complex 4 was achieved through reaction at elevated temperatures. The dehydrogenation of complex 4 by heating in toluene solution formed ethane and alkyl complex 5 when reacted with ethylene.

Summary: The OsO4-mediated reaction can transform mesotetrakis(pentafluorophenyl)porphyrin into a hexahydroxypyrrocorphin, and further reactions can convert it into porphotrilactone. The aromaticity of these compounds is related to the number of lactone functionalities.

Summary: A series of hybrid uranocenes sandwiching uranium (IV) between cyclobutadienyl (Cb) and cyclo-octatetraenyl (COT) ligands have been synthesized, structurally characterized and computationally studied. The bonding in these hybrid uranocenes shows non-negligible covalency, providing new insights into actinocene bonding. These compounds also demonstrate redox-neutral activation of diethyl ether, potentially leading to further small-molecule activation chemistry.

Summary: A series of half sandwich arene-ruthenium complexes containing bis-imidazole methane-based ligands were synthesized and tested for hydrogen production from formic acid in aqueous medium. Among the complexes investigated, Ru(II) coordinated with a 4-methoxyphenyl substituted bis-imidazole methane ligand exhibited the highest catalytic turnover and efficiency for formic acid dehydrogenation in water.

Summary: Triple-negative breast cancer (TNBC) is a highly aggressive form of breast cancer with high metastasis rates due to multidrug resistance. While platinum-based antitumor agents have severe side effects, nickel and palladium complexes are being investigated as potentially safer alternatives. Among these, palladium derivatives have been found to be safer and effective inhibitors of TNBC cell adhesion and migration.

Summary: The importance of aerobic conditions in promoting the reactivities that give functionalized ligands NC(X)N has been established. Furthermore, the significance of oxidation for C-heteroatom bond formation was further deduced from the reaction of the structurally authenticated complex (NCN)Ni(OSiMe3) with CuBr2 to give the C-O functionalization product NC(OSiMe3)N.
