1126-93-8 Usage

General Description

2-Ethoxy-4,4,5,5-tetramethyl-1,3,2-dioxaboralane is an organoboron compound with the chemical formula C8H19BO2. It is a colorless liquid with a fruity odor, and it is commonly used as a reagent in organic synthesis, particularly in the Suzuki coupling reaction, which is a widely used method for forming carbon-carbon bonds. 2-Ethoxy-4,4,5,5-tetramethyl-1,3,2-dioxaboralane is stable under normal conditions, but it should be handled with care as it is flammable and may release toxic fumes when heated. It is important to follow proper safety precautions when working with 2-Ethoxy-4,4,5,5-tetramethyl-1,3,2-dioxaboralane to avoid any potential hazards.

Check Digit Verification of cas no

The CAS Registry Mumber 1126-93-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,2 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1126-93:
(6*1)+(5*1)+(4*2)+(3*6)+(2*9)+(1*3)=58
58 % 10 = 8
So 1126-93-8 is a valid CAS Registry Number.

La[N(SiMe3)2]3-Catalyzed Hydroboration of Esters and Other Challenging Unsaturated Groups

Kang, Zihan,Xu, Xiaojuan,Xue, Mingqiang,Yan, Dandan

, p. 1142 - 1146 (2019)

The commercially available homoleptic lanthanum amide La[N(SiMe3)2]3 (LaNTMS) is reported to enable the hydroboration of esters using pinacolborane (HBpin) as the reducing agent. A wide range of substrates inclu

Palladium on carbon as an efficient, durable and economical catalyst for the alcoholysis of B2pin2

Li, Ning,Liu, Xiang,Meng, Xu,Shen, Jialu,Zhou, Junjie

, (2021)

Hydrogen has attracted much attention as one of the most promising chemical fuel candidates because of its zero emission during consumption. In order to solve the freezing problem of water based hydrolysis process, herein, the Pd/C as an efficient and stable catalyst for the methanolysis, ethanolysis, propanolysis and butanolysis of B2pin2 for the generation of hydrogen has been first developed. The large kinetic isotope effect (KIE) of kH/kD = 5.0, D2 formation from CD3OD and in situ tandem reaction have confirmed that alcohol is the only hydrogen source. Interestingly, the order of Ea of these alcohols in H2 evolution is MeOH (methanol, 29.57 kJ/mol) nBuOH (n-butanol, 41.98 kJ/mol), which is consistent with the known order of acidities of these alcohols (MeOH > EtOH > PrOH > nBuOH).

Super hydride catalyzed ester and isocyanate hydroboration

Behera, Bedabyas,Ding, Yi,Du, Zonggang,Kumar, Arun

, (2021)

Commercially available, eco-friendly lithium triethylborohydride (LiHBEt3, Super hydride) was shown to be an excellent catalyst for the solvent-free hydroboration of esters using pinacolborane at ambient reaction conditions. This was achieved w

Synthesis and characterization of rare-earth metallate amido complexes bearing the 2-amidate-functionalized indolyl ligand and their application in the hydroboration of esters with pinacolborane

Bao, Qin,Gao, Jianjian,Hong, Dongjing,Mu, Xiaolong,Song, Lulu,Wang, Shaowu,Wei, Yun,Zhou, Shuangliu,Zhu, Xiancui

, p. 2953 - 2961 (2022/02/21)

The reactions of 2-amidate-functionalized indolyl proligand 2-(2,6-iPr2C6H3NHCO)C8H5NH (H2L) with [(Me3Si)2N]3RE(μ-Cl)Li(THF)3 were studied leading to the synthesis and characterization of a series of novel discrete trinuclear rare-earth metallate amido complexes containing the anion [{η1:(μ2-η1:η1):η1-LREN(SiMe3)2}3(μ3-Cl)]? and cation Li+(THF)4 (RE = Y(1a), Nd (1b), Sm (1c), Gd (1d), Dy (1e), Er (1f), and Yb (1g)) in good yields by silylamine elimination. All of the complexes were characterized by spectroscopic methods, elemental analyses and single-crystal X-ray diffraction, and complexes 1a and 1c were additionally characterized by NMR spectroscopy. As proof of principle of their activity, these complexes were used as precatalysts for the hydroboration of esters using HBpin as the hydride source displaying high activity under neat and room temperature conditions. As a result, the ligand, ionic and multinuclear cooperative effects on catalytic activity were observed.

Hydroborative reduction of amides to amines mediated by La(CH2C6H4NMe2-: O)3

Gong, Mingliang,Guo, Chenjun,Luo, Yunjie,Xie, Hongzhen,Zhang, Fangcao

, p. 779 - 791 (2022/01/22)

The deoxygenative reduction of amides to amines is a great challenge for resonance-stabilized carboxamide moieties, although this synthetic strategy is an attractive approach to access the corresponding amines. La(CH2C6H4NMe2-o)3, a simple and easily accessible lanthanide complex, was found to be highly efficient not only for secondary and tertiary amide reduction, but also for the most challenging primary reduction with pinacolborane. This protocol exhibited good tolerance for many functional groups and heteroatoms, and could be applied to gram-scale synthesis. The active species in this catalytic cycle was likely a lanthanide hydride.
