Catechol‐Functionalized Polyolefins
Angewandte Chemie International Edition, 2020AbstractThe incorporation of comonomers during ethylene polymerization can efficiently modulate important material properties of the polyolefins. Utilizing bioresourced comonomers for the generation of high‐performance polyolefin materials is attractive from a sustainability point of view.

Reaction of estrone-3,4-o-quinone with ethanethiol and glutathione leads to the formation of 4-hydroxyestrone-2-thioethers. Incubations of [1-3H]hydroxyestrone with rat liver microsomes and NADPH in the presence of glutathione results in the formation of 4-hydroxyestrone-S-glutathione with no release of tritium in the water indicating GSH addition to C-

Abstract Catechol estrogens (CEs) are a major group of active natural estrogen metabolites, formed by aromatic hydroxylation of primary estrogens at either the C-2 or C-4 position. These compounds may participate in the mechanism of estrogen action on the brain and pituitary gland.

Catechol dioxygenases are key enzymes in the metabolism of aromatic rings by soil bacteria. Catechol dioxygenases have been found that participate in the metabolism of halogenated aromatic compounds and, in doing so, play a key role in bioremediation of halogenated pollutants.

Catalytic Aerobic Cross-Dehydrogenative Coupling of Phenols and Catechols
ACS Catalysis, 2019We describe a selective, catalytic aerobic cross-dehydrogenative coupling (CDC) reaction of phenols and catechols that creates aryl ethers. To avoid challenges of selectivity, we employ copper (Cu) coordination to confine substrate redox to the inner ...

Vibrational spectra of catechol, catechol-d2 and -d6 and the catecholate monoanion
Spectrochimica Acta Part A: Molecular Spectroscopy, 1991Abstract The Raman and infrared spectra of normal and deuterated catechol in the solid and aqueous solution phases are reported, together with data for the catecholate monoanion at high pH. Assignments of fundamental modes are proposed.

Analytical Chemistry, 2019
Analyte-responsive chromo-fluorogenic reactions under accessible conditions are important for designing small-molecule spectroscopic probes. We describe a series of newly-constructed motifs based on the chromo-fluorogenic reaction between catechol ...

Iodine‐Mediated Synthesis of Methylthio‐Substituted Catechols from Cyclohexanones
Advanced Synthesis and Catalysis, 2019A novel and efficient I2-mediated direct synthesis of methylthio-substituted catechols from cyclohexanones was developed. Various cyclohexanones underwent oxygenation, methylthiolation, and dehydrogenative aromatization in one pot in moderate to good ...
