Usage

General Description

Dihexyl malonate is a chemical compound with the molecular formula C13H24O4. It is derived from malonic acid and is classified as an ester. Dihexyl malonate is used as a plasticizer in various industrial applications, particularly in the production of plastics and polymers. It acts as a softening agent, improving the flexibility and durability of the final material. Additionally, it is used as a lubricant in the manufacturing of metal products and as a solvent in the formulation of various consumer products. Dihexyl malonate is also used in the production of cosmetics, pharmaceuticals, and food products. However, it is important to handle dihexyl malonate with care and follow safety guidelines due to its potentially hazardous nature.

Studies of the Electronic Effects of Zinc Cluster Catalysts and Their Application to the Transesterification of β-Keto Esters

The electronic effects of tetranuclear zinc cluster catalysts on transesterification were investigated by changing the carboxylate ligands in the clusters. High catalyst activity crucially depended on the balance between Lewis acidity and Br?nsted basicity of the catalyst; this was consistent with the dual activation of both the electrophile and nucleophile by the cooperative zinc centers. In addition, tetranuclear zinc cluster catalysts achieved the transesterification of β-keto esters with unprecedented levels of broad substrate generality, in which a newly developed pentafluoropropionate-bridged zinc cluster and 4-dimethylaminopyridine additive greatly improved the reactivity of sterically congested α- and α,α-disubstituted β-keto esters. Lewis versus Br?nsted: High catalyst activity of zinc clusters on transesterification crucially depend on a balance between Lewis acidity and Br?nsted basicity of the catalyst. Zinc clusters, including a newly developed pentafluoropropionate-bridged zinc cluster, achieved the transesterification of β-keto esters with unprecedented levels of broad substrate generality (see figure).

One-Pot synthesis of 5-Alkylthio-3H-1,2-dithiole-3-thiones: Advantages and scopes

The reaction of dialkyl malonate esters with P2S5/S8 in boiling xylene in the presence of 2-mercaptobenzothiazole/ZnO as catalyst produces 5-alkylthio-3H-1,2-dithiole-3-thiones as major identifiable product. Moderate yields were obtained with malonate esters of primary alcohols. The reaction fails with malonate esters of secondary alcohols. Regarding the substituent in position two, dialkyl malonates with groups such as CH3, Ph, CH2Ph, OCH3 and Cl afford the corresponding 4-substituted derivatives whereas with Br and NO2 do not give the expected products. Some mechanistic evidences are described.

Process for the preparation of 3,5-dihydrocarbyl-4-hydroxybenzylmalonic acid esters

Esters of 3,5-dihydrocarbyl-4-hydroxybenzylmalonic acid are prepared by reacting a 2,6-dihydrocarbyl-4-halomethylphenol with an ester of a 1,3-dicarboxylic acid in the presence of an alkali or an alkaline earth metal hydride. The products are useful as antioxidants.
