Summary: The dissolution of gray selenium in tetraalkylphosphonium acetate ionic liquids was studied using various spectroscopic and analytical techniques. The presence of acetate anions and tetraalkylphosphonium cations facilitated the formation and stabilization of oligoselenides and cationic Se species in the ionic liquid phase. Chemical exchange of selenium atoms was observed, and uncharged cycloselenium molecules were identified at high selenium concentrations. Upon dilution with ethanol, amorphous red selenium precipitated from the solution, while the addition of elemental tellurium resulted in the precipitation of crystalline Se1-xTex solid solutions.

Summary: In this study, trialkyl phosphonium derivatives of vinyl-substituted p-chlorophenol were synthesized using a method involving Grignard reagents. These derivatives showed significant uncoupling activity and antibacterial properties, with the tripentyl derivative being the most effective.

Summary: This study investigated the effect of organic cations on the water adsorption capacity of montmorillonite. The samples were characterized using carbon analysis, N-2 adsorption, X-ray powder diffraction analysis, and infrared spectroscopy. The results showed that the adsorption capacity of water decreased with increasing size of the organic cations. It was also found that montmorillonites saturated with alkylphosphonium cations exhibited higher hydrophobicity compared to those with alkylammonium cations.

Summary: The aluminum analogue of Piers' borane, [HAl(C6F5)(2)](3)1, was prepared on a gram-scale. DFT calculations showed that 1 has a higher fluoride ion affinity (FIA) than Piers' borane, and the Al-H moiety proved to be a strong hydride donor, reacting with alcohol and terminal alkyne to give dehydrogenative products 3 and 4. Hydroalumination product 5 was obtained via the reaction of 1 with aldehyde. Additionally, 1 catalyzes the hydrosilylation of alkynes and alkenes.

Summary: The combination of alkoxyphosphoranes and borane generates zwitterions that act as FLP and can alkylate nucleophiles to form C-C, C-N, C-H, and C-Cl coupling products. A DFT study reveals that the reaction proceeds through an FLP activation pathway, forming an alkoxyphosphonium intermediate that facilitates the alkylation of nucleophiles, similar to the Mitsunobu reaction.

Summary: In contrast to phosphine oxides and arsine oxides, which are stable monomers, stibine oxides are generally polymeric and their properties remain unexplored. In this study, we report the isolation of a monomeric stibine oxide and investigate its bond nature. Furthermore, we demonstrate the diverse reactivity of the stiboryl group, including acting as a Bronsted base, hydrogen-bond acceptor, transition-metal ligand, and participating in addition, exchange, and atom transfer reactions, which differ from its lighter congeners, phosphine oxides and arsine oxides.

Summary: Metal phosphates are significant in the field of synthesis chemistry. In this study, we synthesized and characterized phosphate-catecholate chelated Nd(III), Zr(IV), and Al(III) chlorides (2-5). These complexes were obtained via ethyl chloride elimination reaction of oxophosphoranes with corresponding metal chlorides. The resulting monometallic and bimetallic phosphate-catecholate chelated metal complexes, stabilized by P-O and catecholate-O donors, have potential applications in catalysis.

Summary: Cyclopropenium cations with electron deficient substituents exhibit Lewis acidity despite the presence of π-electrons. The chloride and electron affinities are analyzed computationally and experimentally, respectively. These cations form traditional Lewis acid-base adducts with PPh3, while sterically hindered phosphines lead to frustrated Lewis pairs that participate in FLP additions. Depending on the basicity of the phosphine, addition to alkynes or alkyne deprotonation can occur. In both cases, new C-C bonds are formed, thus expanding the application of FLP chemistry to these delocalized π-cations.

Summary: Phosphine oxides and arsine oxides have highly polarized pnictoryl groups and act as Bronsted bases through O-centered lone pairs. A recent study extended the periodic trends in pnictoryl bonding to antimony for the first time by investigating a monomeric stibine oxide. The study found that as the pnictogen atom becomes heavier, the electronic structure of the pnictoryl bond changes, leading to increased donor capacity of the pnictine oxide.

Summary: Transition metal species readily capture and react with CO, while main group CO adducts and their subsequent reactivity have been less studied. This review focuses on the application of Frustrated Lewis Pairs (FLPs) to develop main group chemistry of CO, illustrating the ability to capture CO and subsequent reduction reactions. These developments suggest that FLPs provide an alternative strategy to enhance the reactivity of CO, promising future advances in homogeneous CO chemistry.

Summary: The reactions of (tBuO(2)CN)(2) with FLPs were investigated. B(C6F5)(3) interacts with the carbonyl oxygen atoms and causes the loss of CH2=CMe2. However, in the presence of basic donors, the protons are intercepted and form salts [Hbase](2) [((C6F5)(3)BO2CN)(2)]. In the presence of (o-Tol)(3)P, a proton transfers to the diazo-N atom and forms (o-Tol)(3)PN(CO(2)tBu)NHB(C6F5)(3). Further addition of B(C6F5)(3) prompts the loss of olefin CH2=CMe2 and CO2, resulting in the formation of (o-Tol)(3)PNHNHB(C6F5)(3). DFT calculations provide insights into the reaction mechanisms and confirm the nature of 5 as a FLP reduction product of a diazene fragment.

Summary: A combination of a phosphinidene precursor, B(C6F5)(3), and 4-ethynyltoluene produced the FLP addition product, Et2N(C14H10)PC(Tol)=CH(B(C6F5)(3))2. Compound 2 reacted with halides, pseudo halides, or Me3SiSPh, providing an easy method for synthesizing salts of anionic phosphines, while the reaction with PEt3 resulted in the zwitterionic species, Et3PCH=C(SiMe3)P(NEt2)C(Tol)=CHB(C6F5)(3)8. This latter species reacted with an alkyne, yielding a phosphine donor with both olefin linked cationic and anionic substituents.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
