General Description

Diethyl 2,3-diisopropylsuccinate, also known as DIIPS, is a chemical compound with the molecular formula C14H26O4. It is an ester with two ethyl groups and two isopropyl groups attached to a succinate backbone. DIIPS is primarily used as a flavoring agent and fragrance ingredient in the food and cosmetic industries. It has a fruity, floral odor that is reminiscent of apple and peach. DIIPS is also used as a solvent in some applications, and it may have potential uses in pharmaceuticals and organic synthesis due to its unique chemical structure. Additionally, it is considered to be relatively safe for use in these various industries based on current available data.

2,3-hydrocarbyl substituted succinic acid diester synthesis and use

The invention relates to synthesis and application of 2,3-hydrocarbyl substituted diester succinate. At a low temperature, carboxylic ester and strong base LDA (Lithium Diisopropylamide) react to form alkenyl alkoxide which is oxidized and coupled by carbon tetrachloride to prepare 2,3-hydrocarbyl substituted diester succinate. Liquid nitrogen has the gas protecting and refrigerating functions by a novel method of introducing liquid nitrogen to a reaction system to perform direct refrigeration. The direct refrigerating method has the advantages of energy conservation, easiness in control of reaction temperature, and replacement of inertial protective gas. The 2,3-hydrocarbyl substituted diester succinate can be used as an electron donor of a polypropylene catalyst.

Synthesis of (arylimido)vanadium complexes and their application for oxidative coupling reactions of silyl enol ether derivatives

(Arylimido)vanadium(v) complexes, V(NAr)(OEt)Cl2 [Ar = C 6H5, p-BrC6H4, p-(MeO)C 6H4] or V(NAr)Cl3 [Ar = o-BrC6H 4, o-(MeO)C6H4] were synthesized by the reaction of VO(OEt)Cl2 or VOCl3, respectively, with the corresponding aryl isocyanates. X-Ray crystal structure determination for V(NAr)(OEt)Cl2 (Ar = C6H5 and p-BrC 6H4) elucidates the alkoxido-bridged dimeric building blocks [V(NAr)(OEt)Cl2]2, wherein the substituent on the benzene ring was found to affect the character of the imido nitrogen. The 51V NMR spectroscopic measurements indicated that the electronic state of the vanadium metal centre depends on the ligands connecting to the vanadium and the substituents on the benzene ring. The selective oxidative cross-coupling reaction of silyl ketene acetal with silyl enol ether was achieved using V(Np-BrC6H4)Cl3 or V(No-BrC 6H4)Cl3.

Oxidative Dimerization of Lithium-Enolates of Esters Promoted by Titanium Tetrachloride

Oxidative dimerization of lithium ester enolates is effectively promoted by TiCl4, which serves as a new and efficient synthetic method.Mechanistic study indicates that the reaction proceeds via a radical-like mechanism, but it is not a free radical process.
