Organolithium reagents are a vital tool in modern organic chemistry, enabling the synthesis of carbon–carbon bonds. However, due to their high reactivity, low temperatures, inert atmospheres and strictly dried solvents are usually necessary for the

The objective of this retrospective study was to compare the effects of the two methods (laparoscopic or laparotomic) of LDA (left displaced abomasum) correction under field conditions by means of survival rate and biochemical profile evaluation. Hol

This paper reports the ability of 1,3:2,4‐dibenzylidene‐D‐ sorbitol (DBS), a simple, commercially‐relevant compound, to self‐assemble as a result of intermolecular non‐covalent interactions into supramolecular gels in deep eutectic solven

From waste to wealth – a self-assembled hydrogel remediates palladium from solution down to sub-ppm levels, and the resulting gel, which has embedded Pd nanoparticles, acts as a green and efficient catalyst for Suzuki–Miyaura cross-coupling react

Regioselective meta-mercuration followed by Pd-catalysed intramolecular bridging gave birth to a novel type of calixarene bearing a single bond bridge between the meta positions of the neighboring aromatic subunits. These bridged derivatives possess

meta-Substituted organomercury calix[4]arenes and their corresponding iodo derivatives have been used for lithiation followed by a reaction with various aldehydes or ketones. The resulting diastereomers were in some cases separable using simple colum

Calix[4]arenes immobilized in the 1,2-alternate and 1,3-alternate conformations were directly mercurated using Hg(TFA)2. The reaction regioselectivity was compared with the thermodynamic stability of the corresponding products obtained by theoretical

Direct mercuration and subsequent transformation of organomercurial intermediates into the corresponding nitroso derivatives enabled the construction of calix[4]arenes bearing azo moieties at the meta position (to the alkoxy groups). These compounds,

By applying electrophilic aromatic mercuration of calix[4]arene the introduction of substituted hydroxymethyl groups at the meta position of the basic skeleton has been achieved. Subsequent intramolecular Friedel–Crafts alkylation led to a novel ty
