The study provides conclusive evidence for an SN2-Si mechanism in the B(C6F5)3-catalyzed hydrosilylation of carbonyl compounds, which has implications for the related hydrogenation reactions. The researchers used a silane with a stereogenic silicon center as a stereochemical probe to investigate the transition state in the B(C6F5)3-catalyzed hydrosilylation of prochiral acetophenone. They found that the reaction proceeds through a concerted SN2-type displacement at silicon, involving a four-centered cyclic transition state, rather than through a free silylium ion intermediate. This mechanistic understanding is significant for the development of catalytic asymmetric approaches and could guide the design of novel processes in synthetic chemistry. The study also suggests that the efficiency of such reactions may depend on the asymmetric induction of a chiral nonracemic borane catalyst.
The research describes a novel method for the preparation of trihydrosilanes, which are synthetically useful compounds, by merging platinum-catalyzed alkene hydrosilylation with SiH4 surrogates. The purpose of this study was to develop a safer and more efficient alternative to the hazardous handling of monosilane (SiH4), which is flammable and toxic. The researchers used di(cyclohexa-2,5-dien-1-yl)silane as a stable surrogate for SiH4, which, when combined with various α-olefins in the presence of a platinum catalyst, resulted in the formation of monohydrosilylation adducts. These adducts, with cyclohexa-2,5-dien-1-yl substituents acting as protecting groups, were then treated with catalytic amounts of B(C6F5)3 to liberate Si?H bonds and release benzene, yielding trihydrosilanes in a two-step process without the formation of salt waste. The study successfully demonstrated the scalability of this methodology and provided an alternative route for the preparation of trihydrosilanes, avoiding the need to handle gaseous SiH4, AlkylSiCl3, and AlkylSi(OEt)3, while only releasing benzene as waste.
The research investigates the unique reactivity of a zirconacycle compound, Cp2Zr{κ2-N(SiHMe2)SiHMeCH2} (1), with a focus on its direct hydrosilylation reaction with formaldehyde. The purpose of the study was to explore the reactions of this compound with a series of nucleophilic and electrophilic agents, as well as its behavior with carbonyls, to develop a rationale for the unexpected hydrosilylation activity. The conclusions drawn from the research indicate that the compound 1, despite containing classical 2-center-2-electron SiH groups, reacts with formaldehyde at the exocyclic SiH to form a methoxysilyl group, a transformation that diverges from the reactions of β-H free analogs. This reactivity is attributed to the metallacyclic structure of 1, which may enhance the reactivity of the exocyclic β-hydrogen or limit non-classical interactions that would otherwise stabilize the reactive β-hydrogen. Key chemicals used in the process include formaldehyde, carbon monoxide, tris(perfluorophenyl)borane (B(C6F5)3), and various donor ligands such as OPEt3, PMe3, pyridine, and DMAP.
The study presents a mild and efficient method for synthesizing 1,8-dioxodecahydroacridines via a three-component reaction involving a 1,3-dione, an aldehyde, and an amine, catalyzed by tris(pentafluorophenyl)borane [B(C6F5)3] under solvent-free conditions. The chemicals involved include 1,3-cyclohexanedione as the 1,3-dione, various aldehydes (such as benzaldehyde, aliphatic aldehydes, and heteroaromatic aldehydes), and different amines (like aniline and 4-fluoroaniline). The role of B(C6F5)3 is to act as a Lewis acid catalyst, facilitating the reaction to proceed at room temperature with high yields of the desired 1,8-dioxodecahydroacridines. The study highlights the advantages of this method over traditional Hantzsch reactions, such as shorter reaction times, milder conditions, and higher yields, making it a significant advancement in the synthesis of this class of compounds, which have applications in pharmaceuticals, dyes, and materials science.
The study investigates the synthesis and characterization of zwitterionic niobium and tantalum imido complexes, specifically focusing on their potential as catalysts for methyl methacrylate (MMA) polymerization. The researchers synthesized various complexes using trichloro derivatives [MCl3(NR)(py)2] (where M = Nb or Ta, R = tBu or aryl) and reacted them with lithium aryloxides (LiOAr) to obtain imido aryloxo complexes. They also employed benzyl magnesium chloride ([BzMgCl]) for alkylation, resulting in tribenzyl derivatives. Lewis acids such as B(C6F5)3 and Al(C6F5)3 were used to generate zwitterionic complexes from the tribenzyl derivatives, facilitating the exploration of their catalytic activity in MMA polymerization. The study highlights the role of these chemicals in modifying the reactivity and stability of high-valent metal complexes for potential applications in polymerization processes.
