ZrCl4-Mg(ClO4)2: Highly efficient bimetallic catalyst for acetylation of alcohol with acetic acid

This work describes the highly efficient acetylation (acylation) of alcohols with acetic acid for the ester synthesis in the presence of newly designed a new composite zirconium (IV) chloride and magnesium catalyst which is used bimetallic acidic catalyst ZrCl4-Mg(ClO4)2, which is formed by grinding ZrCl4 and Mg(ClO4)2 in the molar ratio of 1:2, respectively. Thus, the powder X-ray diffraction, scanning electron microscopy, Brunauer–Emmett–Teller surface area, and thermogravimetric analysis of the ZrCl4, Mg(ClO4)2, and non-calcined ZrCl4-Mg(ClO4)2 were recorded. In each case, structural analysis was carried by grinding the catalyst in mortar and pestle.

Process for preparing monoesters

A process for preparing monoesters comprises the step of reacting at least one diol with at least one carboxylic acid in a biphasic solvent system, the carboxylic acid being sufficiently water soluble to allow esterification to occur, and the biphasic solvent system comprising water and at least one aprotic solvent in which the resulting monoester has greater solubility than in water.

Lipase-catalysed selective monoacylation of 1,n-diols with vinyl acetate

A simple enzymatic methodology for the selective monoacetylation of 1,n-diols (n=5,8) using vinyl acetate is reported. Monoacetylation excesses of 81-87% at 74-90% 1,n-diol conversions were obtained in toluene and diisopropyl ether using Thermomyces lanuginosus lipase (TLL) immobilised on polypropylene powder as catalyst.

Chemoselective acetylation of alcohols, amines, and thiols without catalyst and solvent

Microwave induced rapid and selective acetylation of alcohols, amines and thiols with acetic anhydride was carried out under non-catalytic and solvent free conditions.

Lithium chloride catalysed acetylation of alcohols, thiols, phenols and amines

Lithium Chloride is found to efficiently catalyse the acetylation of alcohols, thiols, phenols and amines with acetic anhydride in excellent yield.

A remarkably simple process for monoprotecting diols

Lipase from pig pancreas (PPL) has been shown to catalyse selectively the hydrolysis of alkane-1,n-diol bis-acetates into the corresponding monoacetate.

Highly Selective Monoacylation of Symmetric Diols Catalyzed by Metal Sulfates Supported on Silica Gel

Several 1,α-diols, ranging from 1,2-ethanediol to 1,16-hexadecanediol, were monoacylated with high selectivity by reaction with esters in the presence of metal sulfates or hydrogen sulfates, like Ce(SO4)2 and NaHSO4, supported on silica gel.Symmetrical secondary diols were also selectively monoformylated, by reaction with ethyl formate.This method of selective esterification is simple and practical.The yield of monoester depends upon both the composition and the volume of the solvent (an ester/alkane mixture).Unsupported NaHSO4 also catalyzed monoacylation, but the selectivity was less than in monoacylations catalyzed by the supported reagent.The selectivity can be explained by the following reasons: (1) monoacylated products are formed selectively because the diol, but not the monoester, is preferentially adsorbed on the surface of the catalysts, where esterification then occurs, and (2) thin diol layers are formed on the surface of the catalysts due to limited solubility of the diols in the solvent.

A NEW METHOD FOR THE PRODUCTION OF 15-HYDROXYPENTADECANOIC ACID

15-Hydroxypentadecanoic acid was synthesized by electrochemical condensation of monoethyl 1,10-decanedicarboxylate with 5-acetoxyvaleric acid at a platinum anode.The acetoxyvaleric acid was obtained in two ways, i.e., by acetolysis of 5-chlorovaleric acid and by oxidation of cyclopentanone by peracetic acid in acetic acid.
