The Role of the Surface Energy of Tannin‐Based Adsorbent Materials on the Lead Removal Capacity in Contaminated Water

Chemistry–Methods, EarlyView.
Sample with low concentration of surface groups presents low surface energy and in consequence low adsorption capacity independently of the specific surface area and micro and mesoporosity. In this work, inverse gas chromatography at infinite dilution was used to associate the surface properties (London component, acid and basic constants, and enthalpy)

Process Monitoring of Lactone Ring Formation and Opening by Operando Attenuated Total Reflectance Infrared Spectroscopy

Chemistry–Methods, EarlyView.
Inline monitoring of chemical reactions using spectroscopy can lead to great improvements in process efficiency and economics. In this work, we performed inline attenuated total reflectance infrared spectroscopy on two reactions involving bioderived lactones.

Sequential Ester Homologation–Nucleophile‐Guided Functionalization: A Chemoselective Access to Thioesters, Amides, and Acids

Chemistry–Methods, EarlyView.
The homologation of esters—in the presence of a lithium carbenoid—to thioesters, amides, and carboxylic acid is reported. By controlling the tetrahedral intermediate collapsing and promoting a series of rearrangements ultimately leading to a high electrophilic ketene, the subsequent incorporation of S‐, N‐, and O‐nucleophilic elements furnishes the ...
