The research focuses on the development of a highly efficient and straightforward method for the synthesis of multi-substituted allenes, which are important structural motifs found in natural and pharmaceutical products and serve as building blocks for various organic transformations. The study utilizes a nickel-catalyzed SN2' substitution reaction of propargyl esters with organic aluminum reagents under mild conditions, yielding multi-substituted allenes with good to excellent yields (up to 92%) and high selectivities (up to 99%). The chemicals involved in this process include nickel catalysts such as Ni(PPh3)2Cl2, phosphine ligands like PPh3, organic aluminum reagents such as AlMe3, and a variety of propargyl esters, which bear different substituents like electron-donating or electron-withdrawing groups, thienyl, pyridyl, and alkyl groups. The methodology provides a useful procedure for the synthesis of tri- and tetra-substituted allenes and demonstrates good tolerance for different propargyl esters. The research concludes that the developed method is effective for the synthesis of allenes and is currently exploring the application of this catalyst to other organoaluminum reagents and propargyl esters.
The research investigates the formation and properties of half-sandwich complexes of trivalent rare-earth metals, specifically focusing on the synthesis of bis(tetramethylaluminate) complexes (C5Me4R)Ln(AlMe4)2. The study explores how steric factors influence the formation of these complexes through acid–base reactions involving Ln[N(SiHMe2)2]3(thf)2 and substituted cyclopentadienes. Key chemicals used in the research include silyl-substituted tetramethylcyclopentadienes (HC5Me4(SiR3)), trimethylaluminium (AlMe3), and various rare-earth metal compounds such as Y[N(SiHMe2)2]3(thf)2 and Lu[N(SiHMe2)2]3(thf)2. The synthesis process leads to the formation of half-sandwich complexes with enhanced electronic and steric unsaturation, which are characterized by their fluxional behavior and unique structural features revealed through IR spectroscopy, NMR spectroscopy, and X-ray crystallography. The findings highlight the potential of these complexes in catalytic applications and provide insights into the associative methyl group exchange mechanisms at sterically unsaturated rare-earth metal centers.
The study focuses on the synthesis and structural analysis of main group complexes using the sterically hindered N,N'-bis(2,6-diisopropylphenyl)-4-toluamidinate ligand (HDippAm). The researchers investigated the reactions of HDippAm with metal alkyls such as n-butyllithium (BunLi), dibutylmagnesium (Bu2Mg), and trimethylaluminium (Me3Al) to produce the mononuclear dihapto benzamidinate compounds [Li(DippAm)(THF)2] (1), [Mg(DippAm)2] (2), and [Al(DippAm)Me2] (3). These compounds were synthesized to explore the steric and electronic effects of the bulky HDippAm ligand on metal complexes, which is significant for understanding their performance in catalytic systems and their potential applications in ethene polymerization. The study also aimed to understand the influence of substituents around the amidinate on the catalytic performance, not just electronically but also sterically. The compounds were characterized by various techniques including FTIR, NMR, and X-ray crystallography to determine their structures and steric properties.
