Ligand bite angle, a common parameter to fine-tune reactivity in transition-metal chemistry, is used for the first time main-group chemistry control and tune Lewis acidity organobismuth cations bearing 2-[(dimethylamino)methyl]phenyl (Me2NCH2C6H4) 2-(dimethylamino)phenyl (Me2NC6H4) ligands. The latter chelating ligand induces shorter C-Bi-N leading weaker Bi-N bond with corresponding lower σ*-acceptor orbital hence exhibiting remarkably higher acidity. Gutmann-Beckett method successfully...
In search of stable, yet reactive aluminum Lewis acids, we have isolated an organoaluminum cation, [(Me2NC6H4)2Al(C4H8O)2]+, coordinated with two labile tetrahydrofuran ligands. Its catalytic performance in aldehyde dimerization reveals turn-over frequencies reaching up to 6000 h-1, exceeding that the reported main group catalysts. The cation is further demonstrated catalyze hydroelementation ketones. Mechanistic investigations reveal and ketone hydrosilylation occur through carbonyl activation.
Abstract Bismuth compounds are gaining importance as potential alternatives to transition‐metal complexes and electron deficient lighter p‐block in homogeneous catalysis. Computational analysis on the two‐coordinate [(Me 2 NC 6 H 4 )Bi] 2+ possessing three electrophilic sites is experimentally evidenced by isolation of [{Me }Bi{OP(NMe ) 3 } ][B(3,5‐C Cl ] . These observations led us generate dicationic organobismuth catalyst, )Bi(L) (L=aldehyde/ketone), NMR spectroscopy solution...
A series of differently substituted 2-(2-hydroxyphenyl) benzimidazoles were synthesized by a coupling reaction involving aryl dibromides and 2-hydroxyphenyl benzimidazole. These ligands react with BF3·Et2O to yield the corresponding boron complexes. The photophysical properties (L1-L6) complexes (1-6) studied in solution state. Among these, L1-L4 L6 displayed aggregation-induced emission (AIE) behavior upon addition water THF resulting sizable enhancement fluorescence intensity....
Boron-β-diketonates are classical emissive materials that have been utilized in various fields, however, boron monothio-β-thioketonates, where one oxygen atom exchanged with sulphur not explored detail. To gain...
Triarylboron compounds have been established as promising candidates in optoelectronic applications.
A novel series of amidinate based boron difluoride complexes have been reported along with their photoluminescence and electrochemical properties.
Abstract The sterically hindered monomeric alkoxomagnesium compound [(Me 6 TREN)MgOCHPh 2 ][B(C F 5 ) 4 ] ( 1 has been used to explore the role of magnesium alkoxides in ketone hydroboration. Experiments and DFT calculations are suggestive a concerted reaction pathway traversing through six‐membered transition state involving Mg−OCHPh , B−H, C=O bonds. Prompted by this hypothesis, we investigated activity [Mg(OCHPh 3 ), which exhibits turn‐over frequency reaching up 59,400 h −1 under...

We demonstrate the catalytic role of aluminum and boron centers in borohydride [(2-Me2CH2C6H4)(C6H5)Al(μ-H)2B(C6H5)2] (6) during carbon dioxide (CO2) hydrosilylation. Preliminary investigations into CO2 reduction using [(2-Me2NCH2C6H4)(H)Al(μ-H)]2 (1) [Ph3C][B(3,5-C6H3Cl2)4] (2) presence Et3SiH PhSiH3 resulted CH2(OSiR3)2 CH3OSiR3, which serve as formaldehyde methanol surrogates, respectively. In pursuit identifying active species, three compounds, B(3,5-C6H3Cl2)3 (3),...
