Summary: A series of platinum complexes with phosphine and isocyanide ligands were synthesized and evaluated as catalysts for photocatalytic hydrosilylation of alkynes. The phosphine-isocyanide complexes showed high yields under violet light irradiation, while the parent phosphine complexes were more efficient under blue light irradiation.

Summary: This study investigated the catalytic activities of platinum complexes on the hydrosilylation of aldimines. The results showed that the auxiliary ligand and donor substituent play crucial roles in affecting the catalytic activity of the platinum center. The hydride complex with less bulky donor substituents exhibited lower activity compared to the thiolate complexes with the same donor substituents.

Summary: The chemistry of (P,C)-cyclometalated complexes derived from naphthyl phosphines [(Np)(P,C)M] is reviewed and analysed in this paper. The three main synthetic approaches, P-chelation assisted C-H activation, oxidative addition and transmetalation, are described and compared. These complexes exhibit high thermal and chemical robustness, and have been shown to be competent catalysts in various transformations, as well as key intermediates in others.

Summary: A series of polyethylene glycol phosphine ligands with N donor were synthesized and coordinated with Co(BF4)2 to catalyze the hydrosilylation of olefins and silanes. The best catalytic effect was achieved when the amount of catalyst was 0.5 mol% and the temperature was 90 degrees C with a reaction time of 5 hours. The catalytic cycle performance was also studied, and it was found that after 8 times, its yield could still reach> 90%.

Summary: A T-shaped Pt-0 complex with a diphosphine-borane (DPB) ligand was prepared. The Pt -> B interaction enhances the electrophilicity of the metal and triggers the addition of Lewis bases to give the corresponding tetracoordinate complexes. For the first time, anionic Pt-0 complexes are isolated and structurally authenticated.

Summary: Two iridium catalysts demonstrated high activity in the solventless dehydrogenation of formic acid, with even better performance observed in green organic carbonates like DMC and PC. Experimental data and DFT calculations suggest that the formation of dinuclear species is the pathway for catalyst deactivation, which can be prevented in the presence of organic carbonates.

Summary: The search for an activator for the catalyst precursor [Co(tpy)Br-2] in the hydrosilylation of olefins with hydrosilane led to the discovery of K2CO3 as an effective activator. The ability of various salts to activate the catalyst was examined and compared, and it was determined that an excellent activator requires low MX lattice energy, high X-nucleophilicity, and a strong Si-X bond.

Summary: The activation of a dibromo Co-terpyridine complex immobilized on a stationary phase (Co(tpy)Br-2@SiO2) as a hydrosilylation catalyst with K2CO3 as the activator was investigated. Good yields were obtained in the catalytic hydrosilylation reactions using Co(tpy)Br-2@SiO2 activated by K2CO3. Both the catalyst and activator were easily separable from the hydrosilylated product, allowing for a reusable hydrosilylation system. The Co(tpy)Br-2@SiO2/K2CO3 system was also found to be applicable in a continuous flow reactor as a catalyst in the stationary phase.

Summary: The industrialization of alkene hydrosilylation catalyzed by cheap metals has attracted attention in recent years. In this study, a [P, C] chelate cobalt(I) complex was found to exhibit higher efficiency and selectivity in the hydrosilylation of alkenes compared to its cobalt(III) counterpart. The catalytic system demonstrated 100% Markovnikov selectivity for aromatic alkenes and almost 100% anti-Markovnikov selectivity for aliphatic alkenes.

Summary: Vinylsilanes are important structural units in organic chemistry. This study reports a catalytic alkyne hydrosilylation method using a porphyrin metal-organic framework with incorporated Pd nanoparticles. The catalytic results show that the catalyst has high efficiency and selective production of E isomer vinylsilane. Mechanistic studies reveal that the cooperation between iridium porphyrin and Pd nanoparticles is the key to the high catalytic activity.

Summary: This study reports a facile approach using cobalt complexes to activate, transform, and functionalize P-4. By selecting appropriate ligands, P-4 tetrahedron can be transformed into a zig-zag chain, forming a new complex. Additionally, the complex can be further functionalized, leading to the formation of novel complexes with unique ligands. These results provide opportunities for constructing new polyphosphorus ligands in transition metal complexes.

Summary: Compounds containing 2-R-4,4-bis(trifluoromethyl)benzo[f][1,3,2]dioxaphosphepin-5-ones undergo spontaneous intramolecular cyclization to form P+-C-O--bipolar ions with benzoxaphosphole and oxaphosphethane rings. These ions further dimerize into carbaphosphatrane derivatives and can be hydrolyzed to form benzo[d][1,2]oxaphosphole derivatives. The structures of some compounds have been proved by X-ray diffraction analysis.

Summary: This study investigates the cyclization of glycylglycine dipeptide in the solid state and determines its temperature range. The use of isoconversion kinetics for determining the reaction's kinetic parameters, including activation energy and Arrhenius constant, is demonstrated. The kinetics of the solid-state cyclization is best described by the rate equation for an autocatalytic reaction. Additionally, the self-assembly of glycylglycine and cyclo(glycylglycyl) from a solution is studied using atomic force microscopy.

Summary: In the presence of [Mo(CO)(4)(cod)], the reaction of cyclopentaphosphine cyclo-(P5Ph5) with ketones (acetone and cyclooctanone) led to the formation of air-stable trinuclear complexes. These complexes contain bis-phosphanido ligands (PPh-PPh-PPh-PPh-CMe2O-PPh)(2-) and (PPh-PPh-PPh-PPh-C(CH2)(7)O-PPh)(2-) bridging a Mo(CO)(3)-Mo(CO)(3) unit. This reaction expands the substrate scope of 1 with transition metal carbonyl complexes and represents the first examples of carbonyl compound insertion into the P-P bond of cyclic oligophosphorus compounds. The structures of complexes 2 and 3 have been characterized by P-31 NMR and single crystal X-ray diffraction. Furthermore, the thermal properties of the complexes have been studied using differential scanning calorimetry (DSC) and fast scanning calorimetry (FSC).
