Usage

General Description

2,2-dimethyl-1,3-dioxane, also known as diethyleneglycol dimethyl ether, is a colorless organic compound with a faint, ether-like odor. It is commonly used as a solvent in various industrial and laboratory applications, such as in the manufacture of dyes, inks, and adhesives. It is also used as a solvent in the production of pharmaceuticals and in the extraction of natural products. 2,2-dimethyl-1,3-dioxane is flammable and should be handled with care, as prolonged exposure to the vapor can cause irritation to the eyes, skin, and respiratory system. It is important to use appropriate safety measures, such as proper ventilation and personal protective equipment, when working with this chemical.

Indium(III) triflate catalysed transacetalisation reactions of diols and triols under solvent-free conditions

Acyclic acetals and ketals undergo transacetalisation in the presence of catalytic quantities of indium(III) triflate (In(OTf)3) and diols or triols under solvent-free conditions to generate the corresponding cyclic acetals and ketals in excellent yield. The methodology has been further developed to encompass a tandem acetalisation-acetal exchange protocol, which provides a facile and high yielding route to cyclic ketals from unreactive ketones under very mild reaction conditions.

Quantitative analysis of solvent effects in highly aqueous media. Application of the SWAG procedures and a critical appraisal of the additivity principle

This paper describes a study on medium effects of 25 monohydric and polyhydric alcohols on the neutral hydrolysis of 1-benzoyl-3-phenyl-1,2,4-triazole in highly aqueous media. Dependences of pseudo-first-order rate constants on molality of added alcohol are quantitatively analyzed in terms of pairwise Gibbs energy interaction parameters for initial state and transition state. Additivity of pairwise group interaction parameters (SWAG procedure) is applied, and the validity of additivity is critically examined. Excellent additivity is observed in series of monohydric alcohols and vicinal diols. In series of polyhydric alcohols, group contributions to the observed rate effects, as expressed in pairwise group interaction parameters, are, however, strongly dependent on the position of hydroxyl groups in the alcohol. This (apparent) nonadditivity behavior is discussed in terms of the hydration characteristics of the cosolvents. The importance of hydration shell overlap in determining medium effects is supported by kinetic data in ternary 1-propanol-urea-water mixtures.
