Usage

General Description

Dibutyl suberate is a chemical compound with the molecular formula C18H34O4. It is a clear, colorless liquid that is insoluble in water but soluble in most organic solvents. Dibutyl suberate is commonly used as a plasticizer, meaning it is added to plastics to make them more flexible and easier to process. It is also used as a lubricant and as a fragrance ingredient in cosmetics and personal care products. Additionally, dibutyl suberate has applications in the production of adhesives, sealants, and coatings. However, it is important to handle dibutyl suberate with caution, as it can cause skin and eye irritation, and should be used in well-ventilated areas.

Direct synthesis of adipic acid esters via palladium-catalyzed carbonylation of 1,3-dienes

The direct carbonylation of 1,3-butadiene offers the potential for a more cost-efficient and environmentally benign route to industrially important adipic acid derivatives. However, owing to the complex reaction network of regioisomeric carbonylation and isomerization pathways, a selective practical catalyst for this process has thus far proven elusive. Here, we report the design of a pyridyl-substituted bidentate phosphine ligand (HeMaRaphos) that, upon coordination to palladium, catalyzes adipate diester formation from 1,3-butadiene, carbon monoxide, and butanol with 97% selectivity and 100% atom-economy under industrially viable and scalable conditions (turnover number > 60,000). This catalyst system also affords access to a variety of other di- and triesters from 1,2- and 1,3-dienes.

Oxidation of cycloalkanones with hydrogen peroxide: an alternative route to the Baeyer-Villiger reaction. Synthesis of dicarboxylic acid esters

The acid-catalyzed oxidation of cycloalkanones C5-C8 and C12 with hydrogen peroxide in alcohols was performed, and dicarboxylic acid esters were obtained as the major products in 53-70% yields. In the first step, geminal bishydroperoxides are generated from five-to-seven-membered cyclic ketones. The Baeyer-Villiger reaction is a side process accompanied by the formation of ω-hydroxycarboxylic acid esters.

Convenient selective monoesterification of α, ω-dicarboxylic acids catalyzed by ion-exchange resins

Symmetric dicarboxylic acids, ranging from pentanedioic acid to tetradecanedioic acid, gave selectively the corresponding monoesters in high yields in the transesterification catalyzed by strongly acidic ion-exchange resins in ester/octane mixtures.
