112-45-8 Usage

Chemical Properties

Different sources of media describe the Chemical Properties of 112-45-8 differently. You can refer to the following data:
1. Clear colorless liquid
2. 10-Undecenal was identified, for example, in coriander leaf extract. It is a colorless liquid with a fatty, green, slightly metallic, heavy, floral odor. The aldehyde can be synthesized from undecylenic acid, for example, by hydrogenation of the acid chloride (Rosenmund reduction) or by reaction with formic acid in the vapor phase in the presence of titanium dioxide. In perfumery, 10-undecenal is one of the aldehydes essential for creating the “aldehydic note.” Mixtures containing undecenals with the double bond in other positions (9-, 8-, 7-) are also marketed and used in fragrances, for example, Aldehyde C11 Iso (Givaudan), Intreleven aldehyde (IFF).
3. 10-Undecenal has a characteristic fatty, rose odor on dilution. It has an unpleasant sweet, fatty taste. This compound tends to polymerize.

Occurrence

Reported found in coriander leaf (Coriandrum sativum L.).

Uses

10-Undecylenic Aldehyde is derived from the reduction of Undecylenic Acid (U788820) which is used for the manufacture of pharmaceuticals, cosmetics and perfumery, including antidandruff shampoos, antimicrobial powders and as a musk in perfumes and aromas.

Preparation

By oxidation of the corresponding alcohol or reduction of the corresponding acid; by passing vapors of formic acid and undecylenic acid over TiO2 at 250°C under pressure; by passing vapors of undecylenic acid and methanol over a manganese dioxidebased catalyst; or by reduction of ethyl undecylenate with lithium hydride and sodium in tetrahydrofuran solution at very low temperature (–50°C).

Taste threshold values

Taste characteristics at 2.5 ppm: fatty, oily and aldehydic with a mandarin, citrus nuance.

Check Digit Verification of cas no

The CAS Registry Mumber 112-45-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 112-45:
(5*1)+(4*1)+(3*2)+(2*4)+(1*5)=28
28 % 10 = 8
So 112-45-8 is a valid CAS Registry Number.

Catalytic oxidation of alcohols into aldehydes and ketones by an osmium- copper bifunctional system using molecular oxygen

Coleman, Karl S.,Coppe, Maurice,Thomas, Christophe,Osborn, John A.

The oxidation of allylic and benzylic alcohols to aldehydes can be carried out at room temperature as low as 25°C with molecular oxygen, in the presence of the bifunctional osmium-copper system OsO4-CuCl acting as the catalyst.

A relay ring-opening/double ring-closing metathesis strategy for the bicyclic macrolide-butenolide core structures

Halle, Mahesh B.,Fernandes, Rodney A.

A concise strategy has been developed for the synthesis of the bicyclic macrolide-butenolide core structures of various natural products with the macrolide ring size ranging from 12- to 16-membered. The bicyclic structure was easily assembled using the relay ring-opening/double ring-closing metathesis strategy. An efficient synthesis of (±)-desmethyl manshurolide has been achieved as an application of this strategy. This journal is

An isocyanide ligand for the rapid quenching and efficient removal of copper residues after Cu/TEMPO-catalyzed aerobic alcohol oxidation and atom transfer radical polymerization

Bulska, Ewa,Enciso, Alan E.,Fantin, Marco,Grela, Karol,Lorandi, Francesca,Matyjaszewski, Krzysztof,Nogas, Wojciech,Piatkowski, Jakub,Ruszczynska, Anna,Szczepaniak, Grzegorz,Yerneni, Saigopalakrishna S.

Transition metal catalysts play a prominent role in modern organic and polymer chemistry, enabling many transformations of academic and industrial significance. However, the use of organometallic catalysts often requires the removal of their residues from reaction products, which is particularly important in the pharmaceutical industry. Therefore, the development of efficient and economical methods for the removal of metal contamination is of critical importance. Herein, we demonstrate that commercially available 1,4-bis(3-isocyanopropyl)piperazine can be used as a highly efficient quenching agent (QA) and copper scavenger in Cu/TEMPO alcohol aerobic oxidation (Stahl oxidation) and atom transfer radical polymerization (ATRP). The addition ofQAimmediately terminates Cu-mediated reactions under various conditions, forming a copper complex that can be easily separated from both small molecules and macromolecules. The purification protocol for aldehydes is based on the addition of a small amount of silica gel followed byQAand filtration. The use ofQA?SiO2synthesizedin situresults in products with Cu content usually below 5 ppm. Purification of polymers involves only the addition ofQAin THF followed by filtration, leading to polymers with very low Cu content, even after ATRP with high catalyst loading. Furthermore, the addition ofQAcompletely prevents oxidative alkyne-alkyne (Glaser) coupling. Although isocyanideQAshows moderate toxicity, it can be easily converted into a non-toxic compound by acid hydrolysis.

SBA-15 Supported 1-Methyl-2-azaadamanane N-Oxyl (1-Me-AZADO) as Recyclable Catalyst for Oxidation of Alcohol

Tian, Yangwu,Guo, Xiaqun,Li, Meichao,Li, Chunmei,Hu, Xinquan,Jin, Liqun,Sun, Nan,Hu, Baoxiang,Shen, Zhenlu

supporting information, p. 3928 - 3932 (2021/05/26)

Herein, we designed and synthesized an SBA-15 supported 1-methyl-2-azaadamanane N-oxyl (1-Me-AZADO) and investigated its catalytic performance for selective oxidation of alcohols under Anelli's conditions. The first example of immobilization of 1-Me-AZADO was very important to advance the oxgenation effectively because this supported N-oxyl has excellent catalytic activity for oxidation of alcohols to carbonyl compounds, and more importantly, it can be conveniently recovered and reused at least 6 times without significant effect on its catalytic efficiency.

3-BocNH-ABNO-catalyzed aerobic oxidation of alcohol at room temperature and atmospheric pressure

Zhao, Yajing,Li, Yutong,Shen, Zhenlu,Hu, Xinquan,Hu, Baoxiang,Jin,Sun, Nan,Li, Meichao

supporting information, (2019/08/06)

A transition-metal-free catalytic system has been developed for selective transformation of alcohol to aldehydes or ketones. The reactions were performed with 3-(tert-butoxycarbonylamino)-9-azabicyclo[3.3.1]nonane N-oxyl (3-BocNH-ABNO) as the catalyst, NaNO2 as the co-catalyst, molecular oxygen as the terminal oxidant, and AcOH as the solvent under room temperature. This catalytic system exhibited broad functional group tolerance. A series of alcohol substrates, including primary and secondary benzylic alcohols, heteroaromatic analogues, primary and secondary aliphatic alcohols, could be converted into their corresponding aldehydes and ketones in good conversions and selectivities.
