METHOD FOR PRODUCING ARYLSILANE COMPOUND CONTAINING HALOSILANE COMPOUND AS RAW MATERIAL

PROBLEM TO BE SOLVED: To provide a method for producing an arylsilane compound with low production cost. SOLUTION: A method for producing an arylsilane compound includes a reaction step for the cross-coupling reaction of a halosilane compound represented by general formula (A-1), (A-2), or (A-3) and an arylboronic acid pinacol ester in the presence of a nickel catalyst, a Lewis acid catalyst, and an organic base (R independently represent an aromatic hydrocarbon group, a heteroaromatic ring group, or a C1-20 hydrocarbon group; X independently represent a halogeno group or a trifluoromethanesulfonyloxy group).

Design, synthesis, and photoelectric properties of v-shaped organic fluorescent compounds with a 1,3,4-oxadiazole moiety

A series of symmetric, silicon-linked organic fluorescent compounds with two electron-deficient 1,3,4-oxadiazole units were synthesized and characterized. The compounds possessed a V-shaped structure with a silicon atom, which weakened π–π stacking, promoting aggregation-induced emission. The compounds were fluorescent in both solution and solid-state thin films. The efficient fluorescent behavior of the materials was confirmed through optical and electrochemical measurements. The compounds displayed excellent thermal stability, with decomposition temperatures exceeding 400 °C. Amorphous films of the compounds possessed high morphological stability. These results indicate that the compounds may be promising emissive and electron-transporting materials.

B(C6F5)3-Catalyzed C-Si/Si-H Cross-Metathesis of Hydrosilanes

The substituent redistribution of hydrosilanes on silicon through C-Si and Si-H bond cleavage and reformation is of great interest and importance, but this transformation is usually difficult to achieve in a selective fashion. By using electron-rich aromatic hydrosilanes, we have achieved for the first time the selective C-Si/Si-H bond homo- and cross-metathesis of a series of hydrosilanes in the presence of a boron catalyst B(C6F5)3. This protocol features simple reaction conditions, high chemoselectivity, wide substrate scope, and high functionality tolerance, offering a new pathway for the synthesis of multisubstituted functional silanes.

Synthesis, photophysical and electrochemical properties of symmetric silicon-linked coumarin-oxadiazole derivatives

A novel, silicon-linked, symmetric, V-shaped, coumarin derivative (1) with an electron-deficient 1,3,4-oxadiazoles unit and a phenyl moiety was synthesized and characterized. An efficient multifunctional organic light-emitting diode material was obtained

Electronic alteration of end-on phenyl groups of bis-triazolyl-silanes: Electron-transport materials for blue phosphorescent OLEDs

A series of modified bis(4-(4,5-diphenyl-4H-1,2,4-triazol-3-yl)phenyl)dimethylsilane (ST), ST-CF3, ST-Me, ST-tBu, and ST-OMe, were designed and prepared by introducing electron-withdrawing groups or electron-donating groups at the 4-

Silicon-containing aromatic poly(esters) derived from bis(4-carboxyphenyl) methyl-r-silane and bis(4-(hydroxymethyl) phenyl)methyl-r-silane. synthesis, characterization and thermal studies

This work describes the synthesis, characterization and thermal studies of poly(esters) (PEs) containing two Si atoms in the main chain, derived from aromatic diacids and aliphatic dialcohols in which the Si atom is bonded to methyl and/or ethyl groups. P

Organosilicon compounds with blue photoluminescence properties

A series of π-conjugated compounds and related Si compounds with blue photoluminescent properties have been prepared. Structures of products were confirmed by NMR spectra and mass spectrometry. Photoluminescent properties are discussed. Based on luminesce

Reaction of silyl(carbonyl)iron complexes with liAlH4 giving methylsilanes: Reduction of a carbonyl ligand and coupling with a silyl group

Treatment of CpFe(CO)2SiR3 (R3 = (pTol)2H, (pTol)2Me, MePh(1-Nap); 1-Nap = 1-naphthyl) with LiAlH4 in ether or THF at room temperature gave CH3SiR3 as a major product in moderate to high yield. The labeling experiments using LiAlD4 and CpFe(13CO)2SiR(pTol)2 (R = H, Me) proved unambiguously that the carbonyl ligand is reduced with LiAlH4 and coupled with the silyl group to give the methylsilanc.
