Transition Metal‐Free Carboxylation of Aryl Boronates in Supercritical CO2
European Journal of Organic Chemistry, EarlyView.Transition metal‐free carboxylation of aryl boronates catalyzed by ZnO is achieved by using supercritical CO2. Cage‐shaped cyclic trialkoxyboronates, which are both nucleophilic and soluble in supercritical CO2, undergo the carboxylation efficiently in supercritical CO2 at high pressure and temperature to give corresponding aromatic carboxylic acids ...

Multicomponent Synthesis of Fluorine‐Containing Bioactive Compounds and Drugs
European Journal of Organic Chemistry, EarlyView.Multicomponent reactions are robust synthetic tools to assamble complex polyheterocycles and other interesting molecular architectures with potential application in medicinal chemistry, including their fluorine‐containing analogues. Fluorine atoms placed strategically into bioactive molecules often enhance essential pharmacokinetic parameters like ...

Multistep Reactions Initiated by Amine‐Based Organometallic Methods
European Journal of Organic Chemistry, EarlyView.The advent of C–H activation and other organometallic methodologies making use of transient directing groups or free amines themselves for the elaboration of amine substrates provides unique access to cascade‐type reactions that can generate significant molecular complexity in one pot. The pursuit of atom‐ and step‐economical pathways to access complex

Optical Determination of the Internal Capillary Diameter Used in Taylor Dispersion Analysis
ELECTROPHORESIS, EarlyView.ABSTRACT In this work, we describe an optical setup to determine the internal diameter of narrow bore fused silica capillary used in capillary electrophoresis and Taylor dispersion analysis (TDA). Indeed, fluctuations up to about ±3–4 µm on the capillary I.D. can generate important inaccuracy on the hydrodynamic radius determination by TDA. Calibration

Ethidium benzoate methanol monosolvate
IUCrDataIn the title salt solvate (systematic name: 8-amino-5-ethyl-6-phenylphenanthridin-5-ium benzoate methanol monosolvate), C21H20N3 +·C6H5CO2 −·CH3OH, two ethidium cations, C21H20N3 +, dimerize about a twofold axis through π–π interactions [inter-centroid separation = 3.6137 (4) Å]. The benzoate anions
