An intracrystalline catalytic esterification reaction between ethylene glycol intercalated layered double hydroxide and cyclohexanecarboxylic acid
An intracrystalline catalytic esterification between ethylene glycol intercalated NiAl layered double hydroxide and cyclohexanecarboxylic acid is developed. It leads to much higher deacidification efficiency than the bulk catalytic reaction. The intracrys

Facile oxidative hydrolysis of acetals to esters using hypervalent iodine(III)/LiBr combination in water
The combination of (diacetoxy)iodobenzene (PhI(OAc)2, DIB) and lithium bromide (LiBr) efficiently oxidized cyclic and acyclic acetals to the corresponding hydroxyalkyl carboxylic esters and simple esters in good to excellent yields. The merits of this reaction are that it employs commercially available and non-explosive hypervalent iodine(III) reagent, water as the solvent, a short reaction time, and mild reaction conditions.

Al2O3/MeSO3H (AMA) as a new reagent with high selective ability for monoesterification of diols
A new facile method for monoesterification of diols has been developed. A variety of diols, in particular oligoethylene glycols, were selectively monoesterified in excellent yields by reaction with aromatic and aliphatic acids in the presence of Al2O3/MeSO3H as a new reagent without use of any solvents.

The Effect of pH Control on the Selective Ruthenium-Catalyzed Oxidation of Ethers and Alcohols with Sodium Hypochlorite
Highly selective oxidations of ethers to esters or lactones and of secondary alcohols to ketones were achieved using catalytic amounts of various Ru precursors and the theoretical amount of NaOCl. Reactions were carried out in biphasic solvent mixtures at constant pH 9-9.5 via either feed-on-demand addition of HCl and NaOH or in the presence of NaHCO3/Na 2CO3 buffer. The catalyst could be easily recycled for at least 4 times with only minor loss in selectivity. Products were generally recovered by simple phase separation and evaporation of the organic solvent. The effects of catalyst precursor, additives and pH control method are also described.

Oxidative ring cleavage of cyclic acetals with hypervalent tert-butylperoxy-λ3-iodanes
(matrix presented) Exposure of cyclic acetals to 1-tert-butylperoxy-1,2-benziodoxol-3(1H)-one in the presence of tert-butyl hydroperoxide and potassium carbonate in benzene at room temperature results in oxidative ring cleavage to glycol monoesters via intermediate tert-butylperoxy ortho esters.

Photoinduced Molecular Transformations. Part 113. One-step Transformations of Cyclic Ethers into ω-Iodoalkyl Formates and of Aldehyde Cyclic Acetals into Monoesters of α,ω-Alkanediols by Iodoxyl Radical
The reaction of cyclic ethers with iodoxyl radical and iodine oxide gives the corresponding ω-iodoalkyl formates in one step; tetrahydrofuran can be transformed into ω-iodoalkyl formate in 31percent yield.Aldehyde cyclic acetals under conditions similar to the reaction of cyclic ethers lead to monoesters of α,ω-alkanediols in one step; cyclohexanecarboxaldehyde ethylene acetal gives 2-hydroxy cyclohexanecarboxylate in 60percent yield.The pathways leading to ω-iodoalkyl formatesand monoesters of α,ω-alkanediols are discussed based on the results of 18O-labelling studies with (18)OI and I2(18)O.
